Alien crash site biomes are biomes which spawn at a distance of 300 and over. These meteors have appeared to crash, bringing valuable items forth from space. As well as containing space rock and space goo, they are defended by vicious aliens. These aliens are blue, and somewhat resemble an orca, as they release an orca-like scream when they see you. These are most commonly nicknamed 'space whales'. As space rock and space goo can be mined only with a diamond or higher tier pick, it is advbisable to be a wealthy avatar. Once these items are mined, you should make laser weapons.
