About the game
You enter dangerous sites with weapons, supplies and a bodycam view. Each map gives your team objectives to complete while creatures hunt nearby. You search rooms for useful items and work out a route through the area. The Frostfall Ridge mission sends you between signal stations in a freezing forest. You solve their terminal puzzles, find warmth and arrange a helicopter escape.
Up to four players share an online session. Your voices can attract enemies, so communication also creates danger. You need to watch for creatures that imitate players and use equipment to draw hunters away. Between missions, you can buy weapons and attachments that remain available later. This is Early Access, with a small set of missions and systems still being revised.
