Free Aliens & Extraterrestrials 3D Models

Aliens and extraterrestrial life forms, including classic grey visitors, insectoid swarmers, bulky brutes and strange tentacled organisms. These free 3D models for games work well in sci-fi shooters, space exploration titles and invasion strategy games. Each free FBX download is game-ready for Unity, Unreal Engine and Godot, and can be recoloured in Blender to create entire alien species from a single mesh.
