finished level 50 with 10 lives left booyah. secret is use sniper towers at the begining. and place lots of frost towers cos they level up awesomely with like 6000damage points
honestly the easiest thing too do is get them all coming out one entrance and just anihalate them with the rocket launcer, gets really boring after lvl 100
big piece of mutated, amputated arses that are wafting mysticly through the big brown abyss of leftovers and are killing off the entire 'multi-universal fast foodal' industry
the best weapon is sword of mastery with 30 attack points, i got it from combat training. the best Armour is the protector's set, with it all and 100 everything pretty much i hit round 42 on normal enemy's. you stop failing drag training at around skill 22
