I think the game is ok-ish. But I maybe did a mistake buing it, becusse exploration and stuff is more my thing. This game seems (as been described) some sort of RTS Counter-Strike... that could be a cool and interesting thing, but not for me.
I guest is normal to not have a refund option, but having one could have be a very good thing. Now.. I will wait till release. Maybe singleplayer is more my thing.
