Tropical Stormfront" has now been released on Android, PC, Mac & Linux ;D
Official Web Site: http://www.operationstormfront.com/
I am using LibGDX and OpenGL ES 2.0 for graphics. LWJGL for the backend on Desktop. I can highly recommend both libgdx & LWJGL ;D
If you want to try the full version, I can send you a license key for Desura, just ask! I tried to create a webstart version too but it didn’t want to work (>50MB). It just borked… Sorry!
