Level 23 can I get through. I have not enough Fire Power to kill all. There are to much ?

This is the first of the hard ones... From now on prepare for the worst!

Repeat again and again some levels you like to improve your weapons, vest and skills.

In this level I played in the part close to the base and left the other, even if it does look wise; I used the assault, recon and rocketeer soldiers.

Good luck!
