Paper Wars: Cannon Fodder is a port to the PSP of iFun4all’s Crap of Defense. Crap of Defense garnered good reviews from several reviewing sites. I never played the iPhone version so I don’t own the rights in relaying comparisons. I believe that the iPhone version was first released with only one campaign and received an update with an additional full campaign. The minis version of this game is armed with three full campaigns as well as more stuff.
