Command Bunker is tough, but a few Hammerheads near the entrances (2-3 each) and a couple foxes and cheetahs are all you really need. Teleport out the level 3 Tough guys if you get into trouble. The earlier the better. About wave 6 put out more Hammerheads and upgrade your foxes. Good luck!

...an upgrade system or more units to keep the game interesting. Achievements would also help. I'm giving it a 3/5. That will easily go up with a few changes though...
We are trying to get Kongregate to add our achievements, if you want to start earning you can get them at out website (http://www.battlecritters.com/prisonplanet/play)
We have also created 4 more new guards that will be making an appearance soon in Prison Planet 2.
Thanks for all the great feedback.
Thanks everyone! We are happy we made such a high rating with our first game. We are already hard at work on Prison Planet 2. The big comments seem to be: 1) More targeting options 2) More content 3) badges
-All coming soon. Happy New Year!
We didn't realize other TD games target "weakest" or other targets. Prison Planet only targets "nearest". Great suggestion. What do you think about setting targeting options on each guard? (nearest, weakest, current, other?)
