This is one of the greatest allegro games out there. Don't let the screenshot above tell you otherwise because the in-game graphics are actually unbelievably enhanced! Great powerups such as speed shoes, shadow, power, and more, make this game a must-get.

This... game... is... scary! It's true that the graphics are not that great, but the horrifying sounds, realistic lighting, powerful monsters, and suspenseful storyline make this game a hair-rising hit! This is an awesome game if you are one of those horror game fans.
