strongest zombie can be found in the beginning, each level gained adds 6 value, choose zombie based on level and value and you will get a powerful zombie.
Finally beat it a 2nd time and got the impossible bade. The best combo is the blood sword with counter and counterx2 if you can get it and throw in the areial support which bombs the boss randmonly if you think you need it, secret weapon which is a third type of bomb that is a combination of the first 2, hits everything like the missiles but with the damage of the big bomb.
I reserached the ultimate soldier and I thought that was supposed to win the game or do something. You can research something you already research and get nothing.

3 Million after 3 hours of play. Aim at 45 degree and immediately use the golden gun to shoot yourself back into the air before hitting grounf to maintain forward and upward speed. use 10 tens and pray for reloads. or just save the golden gun for when you are seriously slowing down.
minigun is not the ultimate gun. you need the satelite for it. it takes nearly all the cash for 6-7 days to max it. just spread 5 satelite at the entrance and anything except for the big robots die.
