A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

More and more players complete the Alien Shooter TD story line and ask us to diversify the process of replaying missions at higher difficulty. We're happy to announce that now killing the final not only gives you satellite weapon but also lets you use all the troop classes at the same time! Right after completing the final mission 7 soldier slots will appear in your inventory and all your army will be at your command. Besides, the new version has a new achievement for killing the final boss and a lot of minor fixes and improvements. Thanks for staying tuned!

This announcement is not directly related to Alien Shooter TD. We placed it here because many of you are curious about our plans for near future, and in particular about the long-waited sequel of our most popular game... Of course we remember about Alien Shooter 3, and we urge to make it - and play it - as much as you do! :) But right now economic situation won't let us make AS3 in the proper way. Meeting and even exceeding your expectations is the least we want. We believe AS3 as just an updated version of AS2 would bring no joy to all of us. So we'd better wait than rush and fail. As you may
