This was a very good game, even if your opponent and the difficulty feels like luck of the draw. I prefer to beef up all of my units, although my brother's strategy was to pick a certain few units and beef them up. These were his picks:
Hammerman
Bronto Rider
Archerman
Axeman
Rifleman
Rocket Launcher (He just thought it was cool, fair enough)
Combat Tank
(Shouldn't be stated that picked the specials as well, if he couldn't play the axeman and combat tank)

I like the game but 3 things:

1: Add Armor and Weapon booster upgrades.
2: Let us make ONE CUSTOM UNIT to use that can get unlimited leveling and abilities/powers.
3: Let us unlock special training modes for Unlimited mode so we can put in what enemies we fight and their levels.

If you complaining about the prada points just train a few lvls and you should have plenty. It could use more story I just fly through the battles without realizing that Ive how many Ive gone through til I get beat then have to lvl up the new characters. All and all a good game to waste time on I give it an 8.

Great gama archer is the really good won 10 battles in a row with him{her} 5/5 ;)

Wow...

im giving you a 9 cause..um i blew through about 5 hours on this game unlocking everyone over and over again and after my 3rd seizure i stopped playing.
the game overall was good. i liked your ideas and what not but the game play was kinda sketchy.
