Metal Corps is a Shoot ’em up action game for former color Palm OS 5 devices.
It’s basically a Super Contra clone with different history and enhanced special effects and game mechanics. It was published on early 2002 on several app portals like Handango, Softpedia or Freewarepalm. And was downloaded more than 120,000 times.
The biggest challenge during development was to limit the memory usage and the process optimization to increase the FPS to the maximum.
The game was entirely developed on Java for Palm using the open source Superwaba virtual machine, with a game framework and classes developed by me from the scratch.
