The House of the Dead 2 & 3 Return, and we feel like we should give two warnings. First, if you haven't completed both games, these screens can be considered spoilers. Not so much of the storyline, but of some of the enemies faced later in the game. That shouldn't be too much of a big deal, since they're old games and it kind of doesn't matter what you're shooting at.
The other warning is that these screens are bloody and gross and stuff. On account of all the zombie ichor. This is especially true of the House of the Dead 3 screens. It seems that Sega figured that the semi-cartoony graphic style of the third game would counteract the disgustingness. They were wrong! Some of those zombies are nasty.
