This Flash game started the next age of the Roflcopter saga by encouraging the development of other ASCII art animations based off of popular Internet slang. In this game (based on the Choplifter genre), one is an Elite ROFLER, manning the ROFLCOPTER, using WASD to maneuver it and the mouse to fire an unlimited supply of bullets shot from the ROFLING gun inside the Roflcopter at the enemy LOLLERskaters (ground units) and LMAOplanes (air units)
