The disputed title is Crossfire, a retro-styled shoot-'em-up originally released for the Xbox Live Indie Games (XBLIG) service in 2010. Following the release of an XBLIG sequel, the series later made its way to PC and iOS devices under the name Super Crossfire.
Developer Luke Schneider researched the title before releasing his game, but didn't notice that online games publisher G4Box launched the similarly-titled free-to-play military FPS Cross Fire for PC platforms in 2009. After recently announcing Cross Fire 2, G4Box filed a trademark dispute against Schneider's game, resulting in its upcoming removal from all available platforms.
"[Super Crossfire] barely makes any money these days, and I'm not spending thousands of dollars to try to fight the issue when I just want to make games," Schneider explains. "I can't say too many bad things about someone who's enforcing the trademark according to the law, though I do think it's completely obvious Super Crossfire is not an attempt in any way to infringe on their trademark, and I also don't think there's any confusion over the two games (arcade shooter vs. online F2P FPS)."
Schneider's game has already been removed from iTunes, and will be delisted from Desura, GamersGate, and XBLIG this Friday. Schneider has considered renaming the game for a future PC re-release, and is currently polling fans for suggestions.
