This Is His BOOMStick
One of the players (thank god he was on our side) has a deep love for big barrels... and with that comes the 6-round rotating grenade launcher. I'm still not quite sure exactly which brand it is but good lord does it ever let out a shout. Not only does he take on whoever might be in the 'White Base' alone (not being able to see anything since it's near pitch-black inside) but he also has the balls to rush in alone.
First shot: Kill
Second shot: Miss
Third shot: Kill from about 2 feet away (woops).
