Eleven layers, 300-plus items, and a simulated body
Players descend as disposable grunts sent to retrieve lost cargo on a hostile alien planet. Each of the eleven procedurally generated layers has its own hazards. The game simulates limb injuries and the cardiovascular system: wounds must be bandaged, infections treated, and blood loss stabilized before the character loses consciousness. Mood also affects survival odds. More than 300 items are available across the full game.
Demo drew more than 500,000 players
The free demo, released April 20, covers the first five layers and drew more than 500,000 players, with about 360,000 wishlists. The demo stays available and will not be updated with the full game's content. The full game adds the later layers, additional characters, and endings. A game-and-soundtrack bundle is also available. The game needs only 500 MB of storage and runs on Windows PC.
Casualties: Unknown is out now on Steam for Windows PC at $22.99, with a 15 percent launch discount. The demo remains free.
