This is rally clear, I mean what you have to do. Today, you are going to cut through groups of aliens. You get on a ranch where the cows are taken by flying sources. You travel through nice 3D area of the Wild West World. The aliens get under you gun in groups and after you clear one are you continue into the next level. The game is full of jokes and funny moments. The life is replenish when you finish with one level and get into the next one. The enemies throw dynamites, grenades and other stuff but when you die you continue form the nearest checkpoint. Nice game from a Spanish developers.
