The Shadow: survive without the use of guns
The Merciful: get 2 friends AND kill Bill using the gun while he's intoxicated
The Lone Wolf: survive without ANY contact nor help from anyone (including Bill)
The Governor: survive by using both your friends as a bait for the zombies
For those wanting to get the governor achievement:
When shooting your 2 friends, you need to do it on the screen where there's the hole in front of your door, and also, DON'T BOTHER WITH CHOPPING THE WOOD AT THE CAR CRASH SITE IF YOU'RE GOING FOR THE GOVERNOR, IT'S A WASTE OF TIME
@Luette, WTF you mean by hackers? The developers themselves decided to close down the games cause so many people were complaining about the arena system, lack of DPs, etc
They better transfer the cards you got to the new Yu-Gi-Oh game, cause so many people spent good money or spent hours and hours on this game to obtain them...
Here's a really great tip: Select the Undeads, and buy halberdier then go to the options and enable auto-send on then just keep sending the halberdiers to one line, keep doing this and you will definitely win
