During gameplay of Ultra Alien Escape, players can collect 3 kinds of power-ups which include a bullet, a shield, and a rocket boost. Every bullet power-up includes 3 bullets and bullets can accumulate. The shield power-up can last 5 seconds, making the player invincible during that time. Finally, the rocket boost allows the player to double jump and move faster for 20 seconds. Players will also need to keep an eye on the UFO’s fuel level and make sure to collect the fuel refills as they become accessible. The UFO will lose 10 fuel every 7 seconds while moving. There are two types of fuel which are depicted as a red little fuel can (worth 10 fuel) and a yellow lightning bolt (worth 30 fuel). There are 3 kinds of obstacles in the game which include iron brick, red brick, and fire. Iron brick is indestructible, but red brick can be destroyed by hitting it twice. The UFO can not touch the fire, otherwise it will lose 50 fuel and respawn at the last checkpoint. Different enemies have different attack methods. The dog will run to the UFO when it comes within a certain range/vision and can take 3 shots to destroy whereas the final boss will shoot bullets at the UFO, has their health displayed above them, and cannot be run into.
