It starts with a The Face , then 8 Zrocos come out. 35 seconds after the battle starts, the first wave of Li'l Bun Bun's come out. (8 exactly) then 8 Zackie Pengs come out ~1 min 25 secs after starting Li'l Bun Bun wave #2 comes out.
Thia atage is harder than it looks because 2 of the 4 enemy waves are lil bun buns,which may cause a serious issue.
For first wave:zrocos.Undoubtably the easiest wave of the 4.Wait for the Zrocos to come near the base,then spam meatshields,crazed ufo and crazed sexy legs.
For second wave:the first lil bun bun wave.Prepare your A. Bahamut for this wave,because he really does the job done.
Also,maglev should be spawned each wave.
For third wave:Zackie pengs.Its harder than it may look...spam your meatshields (except for mohawk),crazed sexy legs,ucrazed ufos and both of your dragons.This wave is hard because if you take a little too long,the 4th wave will appear,
For fourth wave:2nd lil bun bun wave.This is the hardest of them all,because you wont have A. Bahamut ready and if you dont meatshield enough,the lil bun buns will plow through your defenses.
After that,the face isnt much of a problem,so you've already won.Onward to victory!
