Download UFO Onslaught! 3D
UFO Onslaught! 3D is a pretty simple but fast paced shooter game in which you will have to defend your base against the aliens that try to destroy it. In the beginning it will be easy but as you progress through the game you will find it more difficult to destroy the UFOs.
However, as the time passes you will also receive weapon upgrades that are highly recommended to use if you want to have an easier task when it comes to shooting down the UFOs. The three dimensional graphics of the game do not look great but they are good enough.
