Swarm Keeper is a Dungeon Keeper inspired modification for Alien Swarm. It offers the following features: Build a dungeon for your creatures (aliens), imps which perform tasks for you (like digging blocks away, collecting gold), a portal through which creatures enter your dungeon, different room types (treasure, lair, hatchery and training), a dungeon heart, which must be protected from enemies and invading marines as enemies. This mod should be considered as an experiment to bring a Dungeon Keeper like game to the Source Engine.
New version of Swarm Keeper. Non explored parts of the map are now made full black, three new spells, selected blocks for digging are now glowing green and updated sounds. Install Instructions: 1. Extract contents into your sourcemods folder (default location: C:\Program Files (x86)\steam\steamapps\sourcemods). 2. Restart steam. 3. "Swarm Keeper" should now appear in your games list. If you do not have "Alien Swarm" installed, it will ask you to download it upon launching the mod.
