i completed the game and i did not cheat to get survival do a kapow (z-z hold fast) at the very beginning when it says fight and the it KO him then jump on the building on the left and as soon as the enimie comes do a kapow again. do this until you get 10 and you can either keep going or you can just keep dying to get the reward faster and to get vortigon you have to get all the acheivments! surviver acheivment unlocks mechalo from chaos faction 1.
