Rifle Mod is an Alien Swarm server-only mod that forces players to play with assault rifles only, harder aliens, more ammo, smarter bots. However rifle only restriction can be disabled and a number of modifications can be turned on during briefing, see commands. Can be installed on a dedicated server or on a regular game.

Alien Swarm Dedicated server
2. Download Riflemod's server.dll file. See links above
3. Copy with replacement Riflemod's server.dll to swarm/bin
4. Make sure you have sv_allow_lobby_connect_only 0 set in your swarm/cfg/server.cfg to prevent often server crashes
5. Start the dedicated server
You can also host a Riflemod server from the game directly. All you need is to do steps 2, 3 listed above and start the game as usual. But backup the files you're replacing to be able to revert later. Usually Alien Swarm folder is located here:
C:\Program Files (x86)\Steam\SteamApps\common\alien swarm\
