Bought it a couple of days ago.
Currently really enjoying it as something pretty different, playing with my mate most of the time.
If playing it during the day and early evening the game is much more enjoyable as people are pretty chill and it is great teaming up with other people to take down the bigger mechs.
But then at night (they mostly come out at night, mostly) the trigger happy Yanks join the game and all of sudden it goes from a PvE, lets help each other out to PvP all out warfare - Exactly what happened with DayZ mod when originally released, went from PvE game to everyone shooting on site.
The game is no doubt at it's absolute best when you bump into people and help each other loot and take down bigger enemies.
It is a different type of game and really enjoyable.
Only issues is that I think I am probably about 5/6 hours into the game and feel that in 5/6 hours time will probably had enough of it due to lack of maps and content.
Also word of advice.
Only ever wear your original, I am Noob clothing anything that isn't original clothing is a label stating 'Please shoot me on site'
