Release 2.5 - Wu Xing Battles - Patch Notes

Available November 1!

New Hero: Yi-Lin
Yi-Lin is a quick, melee hero who uses her twin swords to devastating effect. Her use of combos can deal devastating damage as well as provide regeneration making her a true force to be reckoned with.

Yi-Lin is not just any accomplished fighter. This woman out of time was the greatest and most loyal warrior fighting in service of her friend, Chang’E, Empress of the White Tiger Empire. In centuries past, the White Tiger Empire and its allies were threatened by certain destruction as orcs and other invaders poured into their kingdoms from the Dark World. Seeing no other solution, the dwarves of Thuricvod evacuated the stone halls of their home on Centre. Fleeing to the safety of their homeworld and collapsing the portals behind them to cut off the invading forces left the White Tiger Empire with few options for its defense and even fewer allies.

Desperate for a solution to protect her people and preserve her empire, Chang’E forged new alliances and agreed to share her powerful rift magic in exchange for the White Tiger Empire’s relocation into the clouds in a bargain with the Jade Rabbits. But the Empire’s preservation came at a high cost for Yi-Lin. Left behind as the eternal guardian of the final rift to the reborn Cloud Tiger Empire, Yi-Lin transformed into the Jade Sentinel she had previously been in name only and began her watch over the Lotus Temple.

For over one thousand years Yi-Lin stood vigilant, waiting. Now a shadowy figure known only as “Reve” has unleashed unstable rifts on the Lotus Temple, renewing the ancient assault on the White Tiger Empire with the hope of reaching their new empire in the clouds. Yi-Lin, the Jade Sentinel has awoken to defend Centre once more against the hordes of orcs, soldiers, and her old enemies – the Wu Xing Dynasty. Learn more in our Designing Yi-Lin blog!

New Faction: Wu Xing - Masters of the Five Elements
  • Wu Xing Soldiers: These soldiers come in four forms: light, medium, heavy, and ranged.  All of the soldiers have magic armor, making physical damage optimal in defeating them.
  • Terracotta Giant: These slow-moving stone giants do not attack players.  Instead, they perform a steady march to the rift, slowing any player that gets too close.
  • Red Panda: Despite being called the Red Panda, these minions are actually blue!  Be careful, these minions cast a powerful speed buff on allied minions.
  • Water Dragon: This hunter minion focuses on players.  Unlike other Hunter minions, this minion has a splash attack, damaging all players within a cone in front of him.
  • Elemental Mages: These mages throw bouncing orbs of elemental energy.

New Battlegrounds
Water Garden - Survival (Apprentice and Master)
The water gardens of the White Tiger Empire appear to be closest to the first attacks by the Wu Xing Dynasty.  Defend three breaches to the best of your ability without too much help from wall traps.

Castle Gates - Survival (Master and Rift Lord), Sabotage, and Endless
Breaching the Castle Gates is a solid strategy for the Wu Xing Dynasty.  Once inside, defending this open map will be a challenge.  Funneling the front gates to one side is imperative.

Midnight Market - Survival (Warmage and Rift Lord) and Sabotage
These marketplaces of the White Tiger Empire are popular night spots.  This seems to be exactly why the Wu Xing Dynasty has chosen to attack them so aggressively.

New Feature: Discord Integration
Discord has remained one of the most popular modes of communication for OMD!U.  This integration will make communication and community building easier than ever! 

New Feature: Weekly Challenge Matchmaking
The community has requested this feature for quite a while.  We are happy to deliver this highly anticipated feature!

New: Imperial Skins
New themed skins have been added for Tundra, Ivy, Midnight, Smolder, and Hogarth.

New Guardian: Jade Empire Guardian
This new guardian is available in Warmage, Master, and Rift Lord chests.

Immobilizes enemies for 2 seconds when attacking them.  Provides 3 coin per second to nearby allies while in combat.

  • The dashboard has been re-skinned for the launch of the Wu Xing Battles expansion.
  • Notification badge logic has been updated.  You'll see fewer and more relevant badges in the dashboard.
  • The chat UI has been overhauled.  The new design features time stamps, channel notifications, and easier browsing of chat channels.

  • New Quests have been added for Deadeye and Yi-Lin
  • New Achievements have been added for Deadeye, Yi-Lin, and Cygnus.

Balance Updates
  • Restricted Section and Temple Graveyard (Warmage) have been made less challenging.
  • Crogon Keep and Eventide Stables (Master) have been made less challenging.
  • Apprentice and Warmage Banquet Hall has been made less challenging during early waves in Sabotage.
  • First wave of Warmage Restricted Section has been made easier in Sabotage.
  • Rift Lord Baths has been made more challenging in Sabotage.

Chaos Trials:
  • The following modifiers have been made less common:
    • Persistent Barricade Rubble
    • No Health Drops
    • No Mana Drops
    • Additional Northmun Archers
    • Ice, Fire, Arcane, Lightning, and Physical Armor
    • Rugged Runners
  • The following modifiers have been made more common:
    • Double Rift Points
    • 5 Rift Points
    • Additional Firefiend Runners
    • Slow Minions
  • "Additional Rift Points" will now be paired with easier modifiers, on average.
  • "Coin Drain" rate has been reduced by 15%.
  • "Additional Order Mages" will no longer roll on Apprentice and Warmage Chaos Keys.

  • Health reduced by 70%.
  • Speed reduced by 30%.
  • Now only spawn 1 Fireling when a Fire Elemental dies.
  • Now more reliably wait 1 second before detonating.When spawning directly from a door, firelings will now play a spawn sound.
    Developer Comment: Firelings were always intended to attack barricades, but when we fixed the bug in the last patch, they became far too powerful.  These changes pull back on the strength of firelings dramatically.

  • Soul collection radius increased 75%.
  • Fixed an issue where the "Jagged Shards" weaver upgrade was not providing the correct amount of damage.

  • Teleportation Staff teleport delay reduced to 3 seconds (from 5).Teleportation Staff will now expire after 90 seconds, regardless of whether or not it is destroyed.
    Developer Comment: This change allows the teleportation staff to be useful, even when a teammate does not have a consumable to apply control effects to an enemy.  In addition, in order to allow melee heroes to deal with this staff, it will now expire after 90 seconds, if not killed.
  • Minions summoned via consumables no longer reward coin or experience.  Base bounties increased in Sabotage to compensate.
    Developer Comment: This change helps create comebacks by making powerful cards more powerful.  In addition, this change also helps solve some inadvertent/unfun strategies that would result in neither team sending minions until sudden death.

Bug Fixes:
  • Elemental minions will no longer replicate when killed by being knocked off the map. Developer Comment: after we fixed this bug, we noticed that many maps need their kill volumes to be updated. As a result, this can still occur, but it will happen much less frequently. Expect more updates in the future on this issue.
  • Fixed an issue where the Serpent Guardian was still being listed as promotional.
  • Fixed an issue with Tundra's Stay Frosty weaver upgrade not providing damage over time.
  • Fixed an issue where resurrected minions would not have the correct amount of health.
  • Fixed an issue where matches could not be restarted if the dashboard was closed.
  • Fixed an issue where the Chaos Key icon would not be shown at full opacity on the login rewards screen.
  • Fixed an issue where minions that were slowed by Stinkeye's Sermon of Speed weaver would not show foot-shackle effects.
  • Fixed an issue where Gabby's hair could get stuck in a falling position.
  • Fixed an issue where the Arcane Bubble Blower could be activated while in mid-air.
  • Fixed an issue where the icon for the "Tundra 1" quest was incorrect.
  • Fixed an issue where Deadeye's fourth ability could play duplicate effects.
  • Fixed an issue where Stinkeye's totems could occasionally fail to hit enemies that are in-range and visible.
  • Fixed an issue where the Chaos Trial information would be shown each time the hero info panel is closed.
  • Fixed an issue where the player would receive an invalid trap placement message when trying to place a trap while orbiting the camera.
  • Fixed an issue where the Saw of Arctos did not display its damage type.
  • Fixed an issue where the teleportation staff would not function if overlapping.
  • Fixed an issue where fire trap were consuming charges faster than intended.  Balance updated to compensate.  Should not result in visible functional changes.
  • Fixed an issue where community events would not always be displayed.
  • Fixed an issue where Scurvy does not attack guardians.
  • Fixed an issue where chest descriptions could overlap quantity descriptions.
  • Fixed an issue where killing a Chaos Crystal near an environmental trap with lightning damage would cause the server to crash.
  • Fixed an issue where Smolder's primary attack could not trigger the swinging mace on Throne Room.
  • Fixed an issue where Chaos Trial wins would provide stars for achievements.
  • Fixed an issue where Sabotage consumables could be used during a go-break.
  • Fixed an issue where the Dashboard would occasionally force players to reconnect to non-matchmade games.
  • Fixed an issue where Temper's Happy Place weaver was not providing a speed boost.
  • Fixed an issue where Deadeye's Deadlier-Eye weaver upgrade was not providing the full bonus to damage.

Free Expansion Wu Xing Battles Launching This Month!

We’re thrilled to announce that the Orcs Must Die Unchained Wu Xing Battles update will be launching on October 25 for PC! This massive update contains three new maps, a brand new faction of enemy invaders, the powerful new hero Yi-Lin, and much more. Update: The Wu Xing Battles update has been delayed by one week due to a technical issue and will launch on November 1.

New Hero

New Maps
Hordes of never-before-seen enemies are invading the White Tiger Empire on three brand new maps and it’s up to us War Mages to defeat them. Defend the White Tiger Empire’s beautiful Water Gardens in Survival mode and hold the Castle Gates in Survival and Endless! Both locations offer strategic challenges with open layouts and not much room for wall traps. The Midnight Market is a popular nighttime location and is under heavy attack in both Survival and Sabotage game modes!

New Enemies
The new Wu Xing invaders are on the march and they bring fresh skills and tactics into the mix! Being masters of the five elements, even the common Wu Xing soldiers and archers have magic armor. Their massive Terracotta Giants do not attack players directly, but slow any nearby players and march faithfully to the rift on their mission of destruction. The “Red” Pandas are real tricksters, casting powerful speed boosts on their allies, and the Elemental Mages throw bouncing orbs of elemental energy. Last but definitely not least, the Water Dragon hunts players, but unlike other enemies of this type it casts an area-of-effect splash attack.

Tune In!
You can get your first look at the upcoming content on the Designing Yi-Lin Insider Access stream this Thursday at 3 pm Central on OrcsMustDie.tv, followed by a reveal stream every Thursday until the update.

Join us as we preview what’s to come with the Wu Xing Battles update!

Just Updated

New Hero: Deadeye

Deadeye is an infamous outlaw with a bounty on her head. With each kill, she becomes stronger and more infamous. Her dual crossbows and explosive arrows make her a force to be reckoned with.

Half elf and half orc, Deadeye was adopted into the elven community of the First Grove as a child and raised as Galadra the trueshot. Accused of her adoptive mother High Warden Naya’s brutal murder, Galadra was narrowly apprehended by Ivy, Warden of the First Grove, losing her right eye in the process and becoming Galadra the Deadeye.

Get the full details on her abilities and development in the Designing Deadeye blog!

New Feature: Community Challenges

Exciting news, War Mages! In-game events have been a frequent question and discussion topic within the OMDU community and this update finally delivers a lot of the technology we need to create fun in-game events.

We'll have a lot more to share about this in the coming weeks as we run a few smaller events before rolling out an Endless Summer event later this year. Well, later this summer to be more specific!

New Feature: Pause

A highly requested feature has finally arrived! We have added the ability for solo and non-matchmade games to be paused by any player. Due to the game being online, we cannot pause forever, but you have a significant amount of time to grab a snack!

Just Updated

New Game Mode: Sabotage

With OMD!U 2.0, we are proud to debut a new mode: Sabotage! This mode introduces a new, head-to-head way to play OMD!U. In Sabotage, two teams battle on separate versions of the same map, competing to see who can finish their waves with the most rift points still intact. However, both teams can meddle in the other's ability to defend their rift by selecting potions, scrolls, and spells that can interrupt, distract, and disrupt the other team's strategy.Whoever has the most rift points left when all waves are completed wins!

Also, beginning with this mode is an exciting new ranking system. Players can compete to become silver, gold, platinum, and finally diamond ranked. Win Sabotage games to become one of the honored few to reach diamond rank! Playerscan also work together to be one of the few guilds at the top of the ranked guild ladder.

Have fun, war mages!


Redesigned: Score System

All leaderboards have been reset to accommodate new score changes.
  • The base score for leaderboards is now entirely dependent on minion kills and combos.
  • Players receive an 8x bonus score multiplier for zero deaths. Each deathwill reduce this multiplier by 10%, to a minimum of 1x.
  • In Sabotage and Survival, players receive a 4x multiplier for zero rift points lost. Each point lost will reduce this multiplier by 5%, to a minimum of 1x.
  • In Endless, each wave completed after wave 5 now provides a 15% bonus to players' scores.
  • The time-score bonus has been reworked and is more significant. If a player hits par time, he or she will receive a 2x multiplier. If a player completes a battleground under the par time, they will receive a >2x multiplier. If a player exceeds par time, he or she will receive a multiplier between 1x and 2x.
  • The combo point timer on minions now pauses while the minion is in the air.
  • Coin is no longer a factor in score.Developer Comment: We were uncomfortable with score being independent from star performance. With these changes, we hope to align perceptions of performing well with higher scores. In addition, these changes should result in combos still being necessary, but not the only consideration in maximizing scores.


Redesigned: Chest Opening Sequence

  • Players no longer need to click through each card one-by-one. Instead,with a single click, all cards are revealed.
  • If players have multiple chests, they can now quickly proceed to other chests to open them.Developer Comment: Back when players were not getting multiple chests as rewards, the slow presentation of cards for chest-opening worked well.However, now that players collect many chests and many cards for upgrades, the chest-opening sequence needed to be streamlined. These changes dramatically increase the pace of opening chests.


Updated: Enemy Heroes Replaced with Mercenaries

We heard your feedback: enemy heroes are not fun to fight. We have created four new mercenaries to replace them that have intelligent AI and will mix up gameplay in different ways.
  • Pride Assassin: An enemy stealth mercenary that will attempt to gank players and run away to heal.
  • Bouncer Bear: An enemy mercenary that escorts minions and tries to forcefully push heroes away. Be careful; he will damage barricades if he steps on them.
  • Dwarf High Shaman: This dwarf mercenary occasionally shields the minions around him, making them invulnerable unless heroes cross through his shield.
  • Chaotic Kobold Wizard: A chaotic kobold mercenary that roams the map, placing crystals that slow players and disable traps.

About This Game

We’re listening to you. Please check out our forums and let us know how we can make the game better for you.

“It’s Orcs Must Die! 3 and much, much more.” – Polygon

“Unfortunately for orcs, it’s better than ever.” – PCGames N

“Unchained undeniably felt like an Orcs Must Die! game.” – Hardcore Gamer

Orcs Must Die! Unchained takes the award-winning Orcs Must Die! action tower defense gameplay to a whole new level with 3-player team-based gameplay! But don’t get cocky, because the stakes are higher, the traps are bloodier, and the invaders are even more ravenous. You’ll need to bring your A-game and a couple of the biggest orc-haters you can find!

Orcs Must Die! Unchained is set in the familiar world of its hilarious fantasy predecessors, years after the finale of Orcs Must Die! 2. With dozens of new rifts and worlds beyond them, heroes have come from far and wide to wage all-out war for control of these magical gateways. In the years since Orcs Must Die! 2, Maximillian and Gabriella have done their best to rebuild the once-mighty Order. Their new enemy, the Unchained, is no longer the mindless horde defeated twice before, but instead an organized army led by its own powerful heroes.

Killin’ Orcs and Smashin’ Dorks

Orcs Must Die!’s classic white-knuckle witch’s brew of action and strategy returns, letting players team up with their friends to lay waste to millions of new invading monsters! Build an impenetrable gauntlet of traps to hack, grind, flatten, gibletize and incinerate foes before they charge into the heart of the rift!

It's Definitely a Trap

The only thing better than building traps for murdering minions is building more traps! Play to unlock traps, then upgrade them to be even deadlier. Players cover fortresses in gleeful torture devices and engineer a variety of hilarious and violent ends for invading minions. Customize a strategy for every battle. The hordes are no match for the powers of elements and physics!

Real Action Heroes

Are you mage enough to defend the rifts? A wide variety of unique and powerful heroes with deep gameplay options offer a plethora of painfully creative ways to stop orcs in their grimy tracks. Old friends Max and Gabriella return to fight alongside a cast of new heroes like Blackpaw, Hogarth, Stinkeye, and Bloodspike. Whether players prefer might and majesty or scum and villainy, there’s a hero for every type of orc-slayer around.

Your Favorite Ways to Slay

Survival mode lets players murder their way to the top of the orc pile in 3-player co-op defense gameplay that every Orcs Must Die! fan will love. Weekly Challenges and Daily Quests give players the chance to unlock extra traps and upgrade parts. Long-time favorite Endless mode has returned in Orcs Must Die! Unchained with expanded 3-player co-op. All new Sabotage mode sets up two teams of three to troll each other with spells and bosses in an action-packed race to the highest score.

All New Sabotage!

Gamers ready for a trap-snapping, spell-slinging, ogre-spudging good time can look no further than Orcs Must Die! Unchained's new game mode, Sabotage! This fast-paced mode is a totally new way to play. Players assemble a team to defend their rift, but at the same time another team is playing on the same map in some… spooky… alternate dimension or something. These other players can distract your team with spells, minions, and huge bosses to make you lose rift points. But of course, players can pay 'em back by doing the same! The team with the most rift points at the end of the match wins.
