the guy never quits hes crawling to reach the next trap even if it takes 10 minutes (BTW you can get v. high scores when you leave the game afk and wait until he reaches the destination)
just get 4 massive cannons (100 dmg) and place them verticaly on class 6 - it creates a wall of death :) :): ) and you 1 or 2 hit all stages
some 1 mentioned about high HP HOW COME ?? when i 1 or 2 hit ai tanks or even 1 hit entire stage
