Alien Carnage / Halloween Harry

Starring hero "Halloween Harry", Alien Carnage is an impressive game with no detail overlooked. Professional musical soundtrack, brilliant full-VGA graphics, non-stop animation and huge start-game and end-game cinematics. If Duke Nukem has a twin separated at birth, it's got to be Halloween Harry! Harry has an armory of weapons he can find and use, besides the devastating flamethrower that he starts the game with. And Harry's jetpack takes him to spots on a level that normal heroes could not reach.

Branches

Depots

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.

Every appinfo change SteamRaw has observed, grouped by changelist. Tags, features, languages, builds, depots, prices and any other key Steam publishes. Tracking since at least 11 September 2026 21:28 UTC (estimated from the earliest recorded change; the exact first fetch was not stored).

No changes recorded since SteamRaw first saw this app. Every future PICS change will be listed here.
