Tame a high level, trust me u wont regret it if ur a low level survivor. If you have genesis 1 then do some races for a gas mask but you will need 1, go to the swamp cave on the islands redwood (look it up on YouTube if you dont know where it is), then kill everything in there and be careful because theres alot of bugs and you will get lots of levels, there are over 150+ bugs in there.
