Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“You can play it from start to finish right now! The whole 15-minute run is already in, along with 3 maps, 11 towers, 6 bases, 3 bosses and Threat Tier II!

A roguelite lives or dies by its balance. Overpowered builds, weak towers and unfair moments only show up once lots of players have played lots of runs. During Early Access, we'll listen to your feedback, polish the game and keep adding content.”

Approximately how long will this game be in Early Access?

“We plan to stay in Early Access for about 6 to 12 months. We haven't set an exact release date yet. We'll launch the full version once the planned content below is in and the balance feels right. If the estimate changes, we'll let you know right away in an update post.”

How is the full version planned to differ from the Early Access version?

“Here's what we're planning right now. These plans may change as development goes on and as we hear your feedback, and none of them has a date yet.

Planned:
- Base Upgrades: each base gets its own scrap upgrade tree (HP, attack, support and base skill), plus achievements for surviving with nothing but your base
- Skins: earn tower and base skins as event and season rewards
- Season Maps: season-only maps with buffs and debuffs, with skin rewards based on your rank
- Credits and Patch Notes: a page with the credits and update history
- Mod Look Preview: see how a tower looks with mod A or B right in its info
- Higher Tiers and New Bosses: tiers harder than Threat Tier II, more varied boss attack patterns, plus new bosses and drones

Ongoing:
- Balance updates based on your feedback
- Quality-of-life and accessibility improvements

You can also check these plans on the Roadmap page in the game's lobby. Everything in Early Access stays in the full version.”

What is the current state of the Early Access version?

“You can play it from start to finish! Here's what's in the game right now:
- A tutorial
- 3 maps (each with different terrain) and Threat Tier II
- 15-minute hold-outs: bosses always give an Extra Pick, and elites sometimes do too
- 11 towers, each with 2 mods and a Lv5 trait
- 65 augments (including 22 mod-exclusive ones) and 11 bonus cards
- 6 bases (including 2 special bases), each with its own main gun and skill
- Elites, 4 special drones, Golden Drones and 3 bosses
- 7 research tracks, new content to unlock, and 12 perks (equip up to 4)
- Tower stats you can check right on the cards and in the Hangar
- A global Steam leaderboard and 23 Steam achievements with in-game rewards
- A Roadmap page
- English, Korean, Japanese and Simplified Chinese

Right now we're working hardest on balance. Based on your feedback, we'll keep tuning how the difficulty ramps up over the 15 minutes, along with the newest augments. We'll also fix translations as you report them.

Your progress is saved on your PC and carries over through updates. We have no plans to reset saves.”

Will the game be priced differently during and after Early Access?

“Yes. As the content grows, we plan to raise the price at full release. If you buy during Early Access, you'll get every update, including the full release, at no extra cost.”

How are you planning on involving the Community in your development process?

“Come chat with us on the Steam Community hub! Post bugs and ideas in the Discussions, and share your thoughts in a review. We'll read every single one!
- Every update comes with patch notes explaining what changed and why.
- Balance changes are based on your reports.
- Your feedback helps decide the roadmap order, too.”

About This Game

Hold out for 15 minutes!

Defend your base against the drone swarm closing in!
Hold the line until friendly reinforcements arrive at the 15-minute mark!
As time goes on, drones get tougher and come in bigger numbers. If your base falls, it's game over!

Level up and craft your own build

Shoot down drones and collect scrap to level up.
Every level-up deals you 3 cards. Skip to repair your base, or pick a new tower, an upgrade, an augment or a bonus and play it your way. Don't like your hand? Reroll it!

  • 11 towers — One upgrade card levels up every tower of that type.
  • 22 mods — At Lv3, choose one of two mods for each tower.
  • Lv5 traits — At Lv5, every tower unlocks its own trait! Autocannon kill shots carry leftover damage into the next drone, and the Railgun starts firing twin shots.
  • 65 augments — From rockets with huge blasts to lasers that bend and split, there are tons of augments to change up your build! 22 of them are exclusive to specific mods.
Opening rushes, the cards you're offered and buff pad locations change every run. No two runs are ever the same!

Use the terrain

Every map has its own terrain. Use it to defend your base!
Towers on high ground get extra range!

Exploit their weaknesses

Energy tears through shields, explosives crack armor, and physical rounds hit bare hulls a little harder. Pick your towers to match the drones coming at you!

Powerful bosses

Survive long enough and powerful bosses will come for you!
  • Carrier — Spews out swarm after swarm of drones!
  • Overmind — Regenerates its shield with Link Nodes and hijacks your strongest tower!
  • Colossus — Fires seeker missiles, raises an energy barrier and lunges at you again and again!
Every boss you take down gives you a guaranteed Extra Pick. The Colossus gives you two!
Elite drones and special drones like Aegis, Splitter, Medic and Hacker join the swarm, too! Shoot down an elite and you might get an Extra Pick or a base repair. And don't let the Golden Drones get away. They drop rare supplies!

6 bases, each with its own skill

Every base has its own HP, main gun and skill. Hit Space to fire off your skill when things get desperate!
Complete hidden achievements to unlock two special bases!

Combos that feel great

Chain your kills to build up combos. Combos climb through 5 tiers, and every new tier earns you bonus scrap!
Hit-stop, flying debris and screen shake make every kill feel punchy. You can adjust screen shake in the settings.

Keep getting stronger between runs

  • 7 research tracks — Spend your scrap in the Hangar on research, and unlock new towers, mods, bases and perks.
  • 12 perks — Equip up to 4 before each run.
  • 3 maps — Outpost Relay, Canyon Transmitter and Ruined Observatory unlock in order, and then Threat Tier II opens up.
  • Leaderboard and achievements — Compete on the global Steam leaderboard! Unlock 23 Steam achievements and earn in-game rewards. Two of them are hidden!

Easy to read, easy to play

  • Bright neon on a dark background! Even when drones fill the screen, you can see everything at a glance.
  • Check tower stats right on the cards and in the Hangar.
  • A short tutorial gets you started fast. Scale the UI up to 145% and pause any time.
  • Play in English, Korean, Japanese or Simplified Chinese, with mouse and keyboard.
