I feel like your health and mana should regenerate every level, therefore I don't have to buy five health potions every time because I was an inch away from death on the previous level!
@veiakas, these hidden units that you are referring to are know as heroes. You have to kill their living form before you can unlock them. The first hero can be found in the last level of the first area. The only thing that is exclusive on Armor Games is one spell that uses past Infector methods.
Here's how you get most of the secret skins. Artist- open credits twice Rocker- Mute the music Orchestra Leader- mute the sound Solider- Visit Hi Scores Blank- Test an empty level on level editor Mummy- Edit a level with thrusters Demon- Shoot 666 dummies Clown- Complete a level in slow motion Prisoner- Don't shoot for 20 seconds Stick man- Load the game 10 times Bear- Shoot 10 dummies after completing a level Bizarre- Get the heart symbol (found on level 42, off the screen on the left side)
Pretty fun game, but it's annoying how on the exact second that you send out troops either to capture a spot or bring in reinforcements, the AI counters it.
I agree with spyke252 there needs to be a way to actually know the end picture while playing, so we know what to do. And also this really isn't "growing" an empire
Pretty good game, however I have to hold my mouse down in order to completely turn, so if I don't do that, I waist a little bit of ammo just to shoot something at a different direction.
