Here is a mathematical study of weapon damage per second.

1. Machinegun Damage: 23;
   Cycle: 70;
   DPS: 328;
   
2. Shotgun Damage: 40;
   Cycle: 900;
   DPS: 578;
   DPS Real: 311;
   
3. Grenade Launcher Damage: 303;
   Damage 1vs1: 375;
   Cycle: 500;
   DPS: 606;
   DPS 1vs1: 750;
   DPS Splash: 200;
   
4. Rocket Launcher Damage: 1050;
   Cycle: 800;
   DPS: 1312;
   DPS Real: 500;
   DPS Splash: 208;
   
5. Lightning Gun Damage: 21;
   Cycle: 50;
   DPS: 420; <- imo now its much too high, will tweak down.
   
6. Railgun Damage: 1050;
   Cycle: 1100;
   DPS: 954;
   DPS Real: 363;
   
7. Plasma Gun Damage: 100;
   Cycle: 130;
   DPS: 769; <- this cant really go over the usuall 400 assumed, even though it looks insane, in practice its normal.
   
8. BFG Damage: 1050;
   Cycle: 1000;
   DPS: 1050;
   DPS Real: 400;
   DPS Splash: 300; <- and this is assuming half splash damage, usually it will insta kill. Perhaps a tone down is in order.
   

Note: "DPS Real" assumes that the enemy has 300 hp and 100 armor, everything that does more damage than that per shot, is reduced to that.
"DPS Splash" assumes half of splash damage being delivered per shot.
Shotguns "DPS Real" assumes half+ of slugs hit (13 total, 7 hits).

Taking a look at the table, lg seems too strong now, and also bfg splash seems to need tweaking. I will try out new values later today.

Actually, that would make them just camp in same room, moving left right.

With high radius, low damage, they are forced to move from room to room, or arround a bigger room.

Worst camp spots are the smallish rooms that are hard to manouver in.

Camp protection organized this way tends to discourage people to camp in such small, tight places.
