Assimilate

“Assimilate” itself is a very simple retro-style game, in the mold of the NES’s earliest titles which were mostly ports from the arcades. You control an alien spaceship named Ossan. The goal of each level is to maneuver Ossan around a series of deadly projectiles and enemies while kidnapping and assimilating the humans below. Scoop up a human with your tractor beam and use one of four tools to convert them into your alien slave.
