Would it be possible for a Soldat port on the PSP(with permission)? The game is only about 12mb and has little graphical demand and could probably run pretty smooth. The analog or directional pad would work well with controls as well. I'm not sure if you could get it to go online via adhoc or wifi, but bots are nice too. If you've never played it, download it here: http://www.soldat.pl/ . It's free. I also apologize if this has been mentioned before.
