Alios is a 'metroidvania'-style action platformer where you play a soldier packed into a mysterious spacesuit, who wakes up in a hibernation chamber on a spaceship, armed to the teeth.
As soon as you get out of the chamber and start exploring the ship, you'll realize why you're armed with two machine-guns: the ship is infested with aliens, and there seem to be no other humans around.
Fortunately, these aliens are pretty easy to kill, as they're not too quick, and ... well, they don't have machine-guns like you do. Meanwhile, besides killing enemies, you'll need to solve a few puzzles in order to keep moving forward through the narrow passages of the spaceship.
Visually, Alios is quite an interesting title; it has a simple character and scenario designs, but it's still nice-looking. The blood effects on enemies are, on their own, excellent.
Alios is a really fun action and platform game that puts aside any narrative element to focus on frantic and direct action.

It is a practical and realistic game in terms of effects, and it is in real time. 2D games continue to succeed in the background
