Oh lol, Ironically, Wheatley makes a great shield. oh, also, how exactly are you supposed to beat it the "right" way? I tried blasters... but they just waste ammo, with the uber thin creeper. And repulsors can only hold it back for so long... the third wave is brutal.
Well, I didn't want to remove all possibilities of cheating, since its sometimes fun. Forgot about repulsors though ;(
Might make version 2 someday, because since now I can't sort those fields in any way, it's a pain to add even more, like for bombs
The only legit way of beating this map is stay where you are, and defend the position until 10:00 minute. This is where GlaDOS takes over the facility, then all you have to do is just go up and destroy the creeper cameras.
In the starting position, there's enough space underneath for reactors.
Also, don't bother yourself fighting over Wheatley's body, the cores will take care of him later on. Damn, I really hoped it was obvious enough xD
