I, Zombie is a real crapshoot; I'd find it hard to believe any streak above the teens could be done without cheating. However,as with any stochastic process, anything is possible. Vasebreaker is a different story. A determined player such as yourself with a sound strategy could play that almost indefinitely. I got bored and quit playing it only a few levels after earning the trophy.
