In run 3, the player controls a small alien as he or she runs endlessly through space. Attempt crossing roadways while avoiding stumbling and falling bricks, holes, traps, and other hazards. If you crash into a wall, you'll have to restart the level from the beginning.
Get moving and do all the jumping and running you can. Your mission is to make it as far as you can in the weird tunnel without crashing into the depths of space below. To determine the aliens' maximum lifespan, you must explore all available walls.
