Here's a quick summary of what's up next with Stone Cold and Camp Fubar:

Stone Cold - Jack knows where you can get some heavier artillery. Unfortunately, on the way there your RV runs out of gas in the middle of a radioactive desert wasteland, leaving you both at the mercy of attacking mutant sand worms and nuclear zombies. To make matters worse, all gas in the area has been seized by a large bandit gang.

Camp Fubar - The spot Jack spoke of is actually an old Army depot. The heavy weaponry is definitely there, but well-guarded by an overzealous Army general with a fierce army (and a dark secret). He won't give up his cool toys without a fight and the place is crawling with zombie soldiers too. Only the strong survive!

These levels will introduce new enemies, new bosses, enemy vehicles (both ground and air), player controlled turrets (limited ammo), new crops, heavier weaponry, and new defense items for your farm.
