There still aren't that many Dreamcast games out than can be called "must-haves", but "House Of The Dead 2" is definitely one of them. But do you need the gun to play it? YES! Otherwise, it will be  nowhere near as much fun and almost impossible to beat it, as the monsters  are often zipping all over the screen at great speed. The game is  extrememly hard anyway, even set on the "very easy" level (!),  and the first few times you play it you will be killed long before the  final battle, but the game would be over far too quickly if it were easy.  The feel good factor from final victory, however, is always worth waiting  for. Every aspect of the graphics is fantastic, the zombies are incredibly  detailed, especially in close up, and the backgrounds are beautifully  realised. Replay value comes from the many different paths you can take  through the zombie-infested town. These paths depend on the speed and  accuracy of your shooting, and you will enjoy replaying the game to try and  hit those tricky targets, and save the innocent civilians, some of which  are extremely difficult to rescue. Also added is "Original Mode"  in which you build up a store of power-ups and life-ups, and even some  bizarre different weapons and character-modifiers that appear in secret  spots in the course of the game. You really need a VMU for this mode,  although you can enjoy the arcade game without one (there are no save  points during gameplay). Add to this the training exercises, and you have  an arcade experience that is not only transported identically into your  living room, but also enhanced with many extras! The game is above all fun  to play, as it requires no serious investment of time or thought. You can  pick it up at any time, and start blasting the undead!
