Weapons you wished you had in a game

[viper]

Do you remember the mission in Silent Line where you had to go through a burning place and go from room to room and turn the sprinkler system on? Remember at the end of that mission you went into a large room and faced one or two mechs? The one had a weapon so large, it had to hold it with both hands. that's the weapon I would like to see!
I am glad that they brought back the four barrel machine gun in SL!
