Alien Creeper is a mob added by Falling Meteors. Alien Creepers are hyper-charged creepers from space, they are added by the falling meteorites mod.They generally arrive when meteorites fall from space and hit the overworld surface. They also seem to spawn randomly while mining meteorite ore making meteorite mining very dangerous. Be sure to have a good escape route. The explosion radius is 4-5 blocks larger than that of a normal creeper.
When you kill it, you have a chance to get a red meteor gem. Alien creepers seem to have the ability to pull the player towards them before detonation, making them especially dangerous to encounter. Thus, it is best to attack them with a bow.
