    About the game

    You wake up after a helicopter crash in a cold northern wilderness, under a strange mist. Part of your science team is missing. You gather resources, craft weapons and gear, and use guns and heavy melee against alien creatures and machines that come out of the mist. You have to keep warm and fed, and the deeper you go, the tougher the enemies get.

    You can play alone or with up to three friends. Your character and the worlds you play in are saved separately, so you can take your geared-up character into any friend's world. Alien seeds you plant change parts of the land. They open new paths and also bring new dangers.

    HAEX is not out yet. The maker plans to start Early Access in 2027 and has not announced an exact date. Until it is out, how it plays with friends is an open question.
