NO!!! Nobody in their right mind would put gore in a Metroid game. If you want gore, go play unreal or quake, Metroid is far above using things like gore to look cool.
oh, sorry to disappoint you then, but MetEngine has blood effects enabled in it, and EVERY enemy which is hit/explodes splatters blood across the level.
And neither I or any of my collaborators is gonna change that due to a stupid poll.
