The real raeson I bought the 'box
I remember playing this in the arcades, dropping quarter after quarter into the machine just to click that plastic gun a few more times. Yes, it's a short game. Yes, you can run through it in about 2-3 hours, maybe less.
But oh, the replayability. And, you also have HoD2 on this game as well. Plus since it's so short, you can pop it in and get a few shots off, hell maybe even beat it, before work or school (for you youngin's).
It's a classic. It's a purchase. Enjoy.
