WARNING: The games difficulty becomes very high when the trophy/achievement is initiated/completed. Hellhound/zombie hoards are seemingly "never ending." It is advised to be prepared before trying Elevate Your Senses! as all players will run an almost 100% chance of running out of ammo before one round ends, but this may vary.
"Having fun!" - Shouted by Samantha Maxis (Demonic Announcer) during a "never ending" hellhound/zombie round.
