'Shortcut' is a mix of subway and desert/canyon theme. Although gameplay is good and design has its good sides there are still some flaws which gives it an average mark. Lightning is mostly good - especially in the warehouse area where boxes generate nice shadows. Lightning could be better - especially in the beginning which feels too bright. Fires in the beginning doesn't have a sound and the whole level feels a bit too silent. There's this one corridor area in the middle of the subway circle which seems a bit unrealistic - a maze like pack of tunnels. However design is mostly average with some average lightning and good locations. Monster/ammo balance is good and there were some neat explosions in the beginning.
