Can some please explain.
Afterpulse. By gamevil (game out first as I know) 
Afterpulse-Elite Army. By digital legends entertainment sl (came out second) 
Is this one a ripp-off; second afterpulse; same game but better performance and less lag (able to play on older phones and Android versions) or is it the same game but with more weapons, maps, new features etc.? 
If it's rip-off or same game with new features and more items; then this need to be deleted removed as the original game is Afterpulse by gamevil
