You start at your safe home base where you upgrade your stuff, craft weapons, ammo and other items. To do this you need supplies. To do that you go to a map and select the region you want. (only two in the early release right now.) When you pick a region it loads with 7 other players. All you need to do is scavenge for parts and items, then get to an exit. Simple enough. You can do this without ever running into someone else by luck or choice. But if you do see someone, or they see you, it's kill or be killed. If you die, you lose everything you came in with and respawn back at home base. REPEAT.
It's a simple game, but can be challenging... goal? Survive, build your base, get more supplies, repeat. But instead of 100 players you only deal with 7 others.
Looking forward to the release of this game. Check it out:
