Client Side Commands

asw_realistic_death_chatter 1

asw_auto_reload 0

Disables the auto reload.

asw_marine_labels_cursor_maxdist 1000

Always show health bars under marines. Good for medics.

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.

asw_flare_g
asw_flare_r

Change the flare colors.

For classic AS fans:

mp_friendlyfire 1
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.
