So I beat the Zombogod after only grinding the second last level a couple of times. Incidentally the last time i beat it without using time stop or air strike. And now on my first attempt at survival i have just reached 5mil, haven't lost a life, only used air strike 3 times and time stop twice, and i'm bored. there doesn't seem to be a difficulty ramp in survival mode.
Given that you need a fully maxed team to beat the Zombogod, i presume everyone is having this issue with survival?
it was a bit buggy... I couldn't build the fire elemental unit
i also seemed to lose control of my troops if i sent them to guard a location i controlled.
overall though a good game, i really enjoyed it although the pace is a bit slow and the AI is paced funny. The neutral guys tend to be overall stronger than the actual enemy... :S
