Bouh! Prepare you to be afraid: here "Bloodshot", one of rare Doom-like on Megadrive. You thought that Doom was ugly and unplayable? You do not have anything yet considering. Let us be in 2050. Earth is about to undergo an extraterrestrial invasion: 12 vessels move towards us, with the firm intention of éradiquer the human race thanks to its crew, composed robot-killers and of a node plasma (not, not a screen plasma...) designed to transform the vessel into atomic bomb maousse in the event of hacking of the orders. To prevent that, one sends to you on each one of the vessel in order to destroy not only the robots but also the node plasma.
