Hello community.
Someone can help me and answer on topic question? 
I think we have big, empty open world, few robots and few ammo and weapons and… that’s all.
What can i do in this game except looting houses? 
Well, what I got from the beta it was that its a great game to play together with ur friends and that there is a story behind why the machines attacked. There is a lot we dont know about the world but I think the devs wanted us to explore the world and find out for ourself.
I agree, it looks really good for coop and it looks like it will still be fun and more challenging solo.
Wait for release and watch/read reviews is all I can really say if you’re having doubts from looking at the previous Dev streams.
