Fieldrunners

[Barachus]

this is probably the most addictive iphone game yet, great stuff

its basically a defend your castle game, you have a variety of weapons to place on that battle and defend it against troops, helicopters, tanks etc

Looks good but I'm not paying 5 bucks for it

I'm currently addicted to this one too. I play on medium difficulty and wave 60 is my current best.
