here is how to play. Run to 40 pps and don't evolve. when reach 40p. press p and evolve next monster which can fly. you can fly over bullets. shooter can only shoot forward. not up and down.(how idiot) so fly over shooter and you can kill them.(only evolve lv2 can kill shooter)
for guys who want to get only lv3 acheviments.
this game is sucks cause, all time. keybord are all stuck and 'gunboat' suddenly just going forward
this happens ALWAYS when you play map 1-4 which has many water holes
you might very close to lv3 but not yet. IGNORE this 1-4 map and play 1~3 maps
if you failed. your xp is not gained so complete 1~3 maps and you will achieve lv 3
and restarting system is sux. no dead ppls revive. no baricade repair option.
and why so many running fatty zombies with weopon?
finding ppls is too hard thogh they are die too easy
