In the dark world of Alien Slayer 3D you will have the misfortune of meeting the universe's worst creatures. They are most likely not very friendly and definitely not fun to be around, as they will try to kill you with every chance they get.
That is why you have to stay on top of your game and always keep focused, otherwise you will become their prey and you will be killed. Pay attention in all directions at the same time, as you never know where danger might jump from and attack you, and do anything you can to stay alive.
