So, Animals run or attack when the visitor gets close, but when the visitor gets close to humans, they continue doing what they were doing.Some survival instincts humans have.
Um, you guys do know that the levels that you unlocked with energy are all saved levels. So its not a waste to get spawn points. You just need to use a unlocked room size ( unlocked by energy ) to use beta stuff unlocked with energy.
I really like the fact that Enemies actually fight with each other. Not team up and fight you most of the time like other games.Its very fun to watch them attack each other and leave you alone, props for this. :)
A few funny things i realised in this game. 1) There are Hanging Balls and Spikey Wheels, Electrocuting Poles, Mincers in the City... Hmmm... 2) They must use some Strong Rope,unable to be cut and pulverised.Only cuttable by Rockets XD. 3) Zombies can kill me but rockets cant.LOL
Wow, were the scientists so smart to calculate where the lift would break down in emergencies so as to put power restorers o.o I guess they placed one on every level XD
