Chris Buffa (Modojo): Contra for iPhone. That's essentially the gist of Star Marine: Infinite Ammo, the latest from Destructopus developer, GlitchSoft. Bathed in nostalgia, this 2D side scrolling blast fest puts you in control of a one-man army out to destroy enemy robots big and small with an impressive arsenal of guns, but you don't need the famous Konami Code to get the job done. Just gems. Lots and lots of gems.
