"impulse 101" will not give you the special weapons added by SMOD Redux due to it's use of the custom weapon slots that were not used in SMOD. It was created to work around a issue with the typical Half-Life 2/SMOD weapons cheat "impulse 101". So far, "giveall" is the only console command specific to SMOD Redux. If your health reaches a certain low point your screen will tint, indicating that you need to seek cover. Health pickups and Health chargers no longer give health when it is enabled, instead your health will automatically regenerate after a few seconds if you suffered damage. On the "Realistic" SMOD gamemode, the typical system of picking up items to restore lost health is replaced by a regenerating health system similar to the one used in the Call of Duty games. Even "story critical" ones like Alyx and Barney are no longer invincible to your weapons. Now you can hurt and even kill allies much like in Half-Life 1. On the "One Per Category" setting you are limited to carrying one Melee weapon, one Pistol, one SMG, one Rifle, one Shotgun, one "Special" weapon (EX: Gauss, Laser gun), and one Grenade-type weapon. Should you choose to enable them through the Menu System, your maximum amount of weapons may be limited to carrying 15, 8, or one per category at a time. It is highly recommended to use the ironsights in the "Realistic" gamemode to maintain accuracy.

Instead they will drift around your view as you look, similar to the system used in the realism-based shooter Red Orchestra. On the "Realistic" SMOD gamemode, your weapons are no longer "locked" to fire at the center of the screen. On higher SMOD difficulty levels Combine Soldiers can and will take advantage of this feature against you!

The amount of penetration varies between weapons. When the SMOD Weapon/Movement Realism setting is set to "High", The shots fired from most high-powered weapons will go through thin walls and weaker materials like wood and cardboard. It is recommended to shoot enemies in areas that their shields do not cover when possible. The shields absorb any damage from attacks that impact the shield until it breaks. On higher SMOD difficulty levels, the Combine will begin to equip riot shields to better defend themselves against attacks.
