Alien Terminator is an action game in which you have to defend the Earth from the aliens. Apparently, some aliens invaded Earth and are destroying everything on their way. The humans discovered that they have their bases on other planets and your job is to destroy them with a super truck that has recently been invented. The truck possess different weapons that are necessary to kill targets and aliens. They all have specific powers, so you must use them wisely to take the biggest benefit from them. As you play, you will also find power-ups and bonuses that help you finish your levels faster and more easily. Every level has a specific goal that you must achieve in order to get to the next one.
Unfortunately, the game only includes one main mode and offers no multiplayer option. The controls are also a bit awkward and uncomfortable, but you can change them from the options.
Regarding the graphics, they are nice and attractive. Sound effects are good and the music is suitable, but a bit repetitive.
All in all, Alien Terminator is a futuristic action game that will surely attract many players, specially because it is absolutely free.
