VERY GOOD SURVIVAL HORROR GAME. GET IT. YOU WON'T BE DISAPPOINTED.
You play as John Constantine. You have to fight your way through Earth and Hell fighting demons using a vast array of weapons and spells. Weapons include the Holy Shotgun, pistols, crossbows and others. Spells are very good too.
Bosses in the game are various but none of them are too hard. Enemies range from demons to two headed spirits that shoot energy spheres at you.
All in all, an excellent gaming experience and I highly reccommend it to all fans of the survival-horror genre.
