You can! 

  The Commands

These are useful commands to enhance your alien swarm experience. You use these by entering them into the developers console. To do this, go to options, keyboard/mouse, and checkmark enable developer's console. The default key is the ~ key.

To make these commands automatic so you no longer have to enter them every time you start up the game, you must create an autoexec file in: C:\Program Files\Steam\SteamApps\common\alien swarm\swarm\cfg

Create a file in notepad named "autoexec.cfg" (Include the quotation marks when you save it under saveas!) Place any console commands you want to be entered within that file. Alternatively, try placing them in the newmapsettings.cfg file in the cfg folder.

Client Side Commands

asw_auto_reload 0 

Disables the auto reload.

mat_grain_scale_override 0

Removes the grain effect on the screen.

asw_camera_shake 0

Removes the camera shake effect when hit by an enemy.

asw_fast_reload_under_marine 1

Places a fast reload bar under your actual marine so you don't need to look in the corner to time your reload. Or rely on the poor cursor fast reload bar.


Change the flare colors.

exec 360_controller_pc.cfg

enables Xbox 360 controller support. See also WildBill's modified configuration. Courtesy shackanaw

asw_hide_marine 1
asw_controls 0

First one enables firstperson mode, second one hides your marine so you can see, third one changes the camera controls to be more FPS like.

For classic AS fans:

asw_marine_ff_absorption 0 (classic ff damage makes a return)
asw_marine_ff 0 (weapon lock/anti TK Guard mode[!!!]) or 1 (default; Guard off)
asw_marine_ff_guard_time 5.0 (Weapon lock time in seconds; default value. Set to desired duration, or make it indefinite for Moses.)
asw_sentry_friendly_fire_scale 1 (Sentries damage and kill players who get in the way)
asw_weapon_safety_hull 0 (Default; dictates how willing AI is to shoot you to get at Swarm. May or may not make Sentries decide to not kill you if you're in the way, a very valuable fix for the Flamer Sentry if so. Play with the numbers and post your results!)

Note: Some of these do not work in multiplayer.

Dang, crazy. My computer struggles to run this on the lowest of settings though. I'm sad.

asw_fast_reload_under_marine 1 should be default. With that enabled you actually use active reload.
