What is Whisper Mountain Outbreak like?

An isometric co-op survival horror game where up to four of you explore abandoned buildings on a fog-covered mountain, fight waves of monsters, craft items and solve puzzles to escape.

Monsters arrive in waves and you fight them with melee and ranged weapons, heal with herbs and revive downed teammates. Between fights you scavenge resources, craft items, find keys and solve puzzles to open doors, and proximity voice chat is built in.
