Avalanche Studios is self-publishing a new, open-world survival game called Generation Zero. The studio released a new in-depth gameplay trailer dissecting their upcoming multiplayer game.
In Generation Zero players take the role of a teenager who returns to Sweden after a weekend getaway with friends only to discover that the world has been taken over by machines. Exploring a vast open world, players create their own 80s teenage protagonist and set about looking for anything to help them survive against the various machines that now roam the world.
True to most survival games, players will have to find their own weapons and ammo in the world and use whatever else they can find to defeat the machines that have taken over their land. The enemies are persistently simulated so if you fight them but end up fleeing (a recommended tactic in Generation Zero) then they will still be there, waiting to finish the job. There will even be enemies that spawn and won't be encountered for days if you don't come across them.
Generation Zero will also allow online co-op for up to four players in seamless multiplayer. From the trailer, it looks like you'll have to work together in order take down even the smaller machines. Considering that you're just humans and they've got machine guns mounted to their armored bodies, it's probably a good idea to stick together.
Avalanche is planning a closed beta sometime this fall, with more information available at the official website. Avalanche is currently also working on Just Cause 4 with Square Enix and Rage 2 with id Software and Bethesda.
