Client and server update

Update 28-1-2018: Server update also live on AEast. We have a known bug where the points generation is crazy for spotting targets, there is no known date for deploying the fix yet.
Gameplay - Towers now prioritize targeting ships over missiles (Radulfr) Bug fixes - Steam achievement "Your probe spotted a high value enemy target!" should now be working. (Xynth) Utility AI (Radulfr) - Tech constructors do not auto-build on an available rock anymore. Instead they move to it and request orders. - Miners will avoid going into sectors which have bases from both sides. - Miners will consider sectors that are entirely surrounded by friendly sectors as safe to mine in. (Also tech cons will look for their rock there.) - When miners start going to a new sector to mine, a notification will be shown to everyone on the team on the bottom of the screen. - When docked in a station which has enemies nearby, miners will be more hesitant to undock without being ordered to. (Without being ordered to stay docked) - When sending a miner to a sector without specifying a task, a reasonable one is chosen right away instead of once the miner is in the sector. This prevents the miner from going straight back to the previous sector. The miner docks if damaged or full, mines otherwise, and If neither can be done, it will move to the center of the sector. This does not apply to unexplored sectors. - Miners will not go back to the previously mined He3 asteroid, if they can't fill 50% of their cargo on it. Instead they will look for the best rock after unloading, which may still send them back to the previous rock. - If being sent to a sector by a player command, the miner will remember the sector. After unloading, it will first check if anything more can be mined in that sector. Training changes' effects on Phoenix faction - Drones don't ram their target anymore - Drones stay in range better and don't overboost as much - Drones will stop shooting unseen enemies after a few seconds - Drones will look for a new target when their's is unreachable - Drones can be set to defend a target and act semi-smartly - Drones can land on a carrier


After some delays we have just released a new update for you. Steam should automatically update the game for you. Let us know what you think on the forum or the discord!

We also have some server updates ready which we will hopefully be able to release soon, stay tuned!

Gameplay - Changed the interceptor's default loadout to only have one pulse probe equipped (Radulfr) - The autopilot will try to land on a carrier it is sent to. (Radulfr) - Firing the boosters sets the throttle to 100% (Radulfr) UI - Showing hover text for in-game objects in the Command View (and free mouse mode) (Radulfr) - The Command View can be moved with the side-thrust keys (Radulfr) - On trying to map a used key, the "Map Keys and Controls" panel shows what the key is currently bound to. (Radulfr) - Removed confirmation dialog when quitting the game (Loran) - Implemented a separate UI system based on the old UI system and the Lua programming language. Not yet shown by default. (Rock) - Merged introscreen, motd and server browser into this new UI (Bunny, Rock) - Implemented new credits screen (Rock) - Added "Use old UI" toggle in esc->game to switch between the new and old UI. Old UI by default for now. (Rock) General Graphics - Debris (Starfield) now has a little more flying stars at slow speeds on all settings (LANS) - Added setting to change debris density (LANS) - High resolution texture pack is used by default (Blacksun, Rock) - Created low resolution mod package, available on github for now (Rock) - Removed "Use high resolution textures" configuration toggle in the options menu. The /Textures directory is now always used, but this method is deprecated in favour of using the /Mods directory (Rock) - Removed "Use texture pack" option and related code. It likely broke a few releases ago. (Rock) - Removed lots of obsolete code related to texture manipulation (Rock) - Changed font rendering method in some places to allow for scaling fonts (Rock) - Changed how artwork files are loaded by the game. It should not be necessary anymore to change/overwrite files in Artwork. Next to your "Allegiance.exe" and your "Artwork" directory, create a "Mods" directory. For each mod package, create a directory inside this "Mods" directory. The game will look through these directories before falling back to the default artwork. (Rock) Sound - Implemented code for side thrusting sounds, currently still points at the same sound files as forward thrust.(LANS) Bug Fixes - Fixed client crashes with team names having % characters in it (Rock) Training (Radulfr) - Major improvements for wingman AI. - Lots of online capabilities ported to offline. - All used in training mission 6. Also enemy waves for it and stuff. - Increased volume and reduced noise for training mission 7 speech.

“Allegiance, the multiplayer space-combat game from the minds of Microsoft Research, combines the challenges of tactical squadron-based combat, intense one-on-one space dogfights, and amazing graphical and sound effects into a space-action experience like nothing you've seen before.”
86% – MetaCritic

“Its real-time strategy elements and its focus on cooperative piloting tactics are so central to its gameplay that Allegiance can be very challenging to learn, but it's well worth the effort.”
87% – GameSpot

“But if you've got the patience to become familiar with all the controls, and you're willing to work within the framework of a team, and you've got the chance to train and drill with a squad, then Allegiance can be very rewarding.”
82% – IGN

About This Game

Space Combat Action / Simulation

Allegiance uses a unique Newtonian flight model which perfectly balances fun with flight. Space ships turn, slide and boost. You have fluid control of your ship in a wide variety of combat types. Select an agile scout, a hidden stealth fighter, an in your face interceptor or an all around fighter. Or, perhaps you would like to team up with a few friends and pilot a base killing bomber while your friends man the turrets. Get even bigger in a full line of capital ships with better fire power, and even more turrets, and a wide range of support ships all controlled by your teammates. Play it your way; even the sky is no limit.

Real Time Strategy

Allegiance is also a fully formed RTS with tech trees, exploration, base building, and resource gathering. But there’s a twist: most of your ships are flown by real human beings! As the commander of your team, you bring your strategic vision to life by gives direction to the team from an overhead command view. Allegiance melds RTS elements like steering expansion by building new bases, investing in technology upgrades to a seamless command experience designed to help you lead your team to ultimate victory.

Unique Gameplay

Allegiance is easy to learn. Hop in a ship and start flying. Get with a wingman and start achieving your goals: exploration, map control, research and resource collection and best of all, end game dominance. Allegiance is deep. Dip in your toes in for some quick combat or dive all the way in for a rich and rewarding experience.
Most matches average forty minutes, with some competitive matches going the distance for two hours or more. Play for a bit or for a whole match. Or better yet, stay and play for a bunch of matches.

Unique fog of war system
Like many RTS games, you start with most of the map undiscovered. Maps are broken down into several sectors connected by wormholes, which contain resources vital to your team’s survival. But not only finding resources, but also observing the movements of the enemy is vital to your team’s success. Each team has a shared view of the world, seeing only what at least one of its scanners (from ships, bases and deployed sensor probes) picks up. This results in various levels of stealth, misdirection, spying and surveillance emerging.

Economy and Base Building
Economy is key in Allegiance so both hunting enemy miners and defending your own is essential. Base placement drives miner offense and miner defense. Ensuring your own bases build in a timely manner is vital to your success.

Technological Upgrades
As the game goes on, the commander invests money into better technology. The ships you fly become more and more powerful, until instead of lowly scouts and fighters, you’re piloting massive capital ships with several turret gunners each, facing off against swarms of heavy interceptors with powerful weapons.

Countless Tactical Options
Every match is played between teams picking different factions, lead by commanders with different mindsets and divergent leadership approaches, with different players of varying playstyles, emphasizing different technology research paths and expansion strategies.
The end result is almost limitless replayability.
