You're joking right?
A shitty engine, with all the same textures, and models from that fail BattleINC game.
Map isn't anywhere near as big as DayZ, graphics aren't as good.
Its obvious the game went into development about a month after DayZ became popular.
It wasn't announced until then, the website wasn't created, and there was no proof that it was real up until a few days ago.
And by the looks of it all they did was add zombies and some slight engine tweaking to add some survival items.
Its a crappy knock off to make some quick easy money.
They're latest scam is asking people to pay the full price of the game to get alpha access, that way they make their money before people realise how crap it is.
