Open the console menu using ~ and imput this code: bind key command This binds a console command to a key. Note that if the command has arguments, quotes must be used. For example: bind x "impulse 101" Be careful on which key you choose. If you use a key already in use for the game (W, A, S, D are for movement, 1-6 is used for weapons, G is for gravity gun, etc), the bind command will override the original command, and you will not be able to use it anymore.Code Effect bind X "Impulse 101" Creates a hot key for instant stock of weapnos and ammunition using the "x" key Console Codes Use the [~] key during gameplay to bring up the console and enter the following codes there: Code - Effect: sk_plr_dmg_357 # - # is new damage value for .357 Magnum sk_plr_dmg_crossbow # - # is new damage value for crossbow sk_plr_dmg_crowbar # - # is new damage value for crowbar sk_plr_dmg_grenade # - # is new damage value for grenades sk_plr_dmg_pistol # - # is new damage value for pistol sk_plr_dmg_ar2 # - # is new damage value for Pulse Rifle sk_plr_dmg_rpg_round # - # is new damage value for RPG rockets sk_plr_dmg_buckshot # - # is new damage value for shotgun sk_plr_dmg_smg1_grenade # - # is new damage value for SMG grenades sk_plr_dmg_smg1 # - # is new damage value for submachine gun sk_max_357 # - # is new max ammo for .357 Magnum sk_max_crossbow # - # is new max ammo for crossbow sk_max_grenade # - # is new max ammo for hand grenades sk_max_pistol # - # is new max ammo for pistol sk_max_ar2 # - # is new max ammo for Pulse Rifle sk_max_ar2_altfire # - # is new max ammo for Pulse Rifle energy orbs sk_max_rpg_round # - # is new max ammo for RPG sk_max_buckshot # - # is new max ammo for shotgun sk_max_smg1_grenade # - # is new max ammo for SMG grenades sk_max_smg1 # - # is new max ammo for submachine gun sk_max_smg1 # - # is new max ammo for submachine gun net_graph 1 - a more thorough fps display noclip - Ability to walk through walls (Server Side Only) sv_cheats 1 - Activates Cheats viewmodel_fov # - Adjusts size of the weapon you're carrying (54 = default) impulse 101 - All Weapons cl_showpos 1 - brings up position display in top right of screen (0 removes it) getpos - can be used to get current coords for use with setpos skill # - change skill level (# = 1, 2, or 3) air_density # - Change the density of air.

Then bring up the console again and type in changelevel (then the map name) e.g changelevel d1_trainstation_01 (taking you back to the start BUT DONT change the map as this will reset the weapons and you wont get the graivity gun). Then if the gravity gun isn`t available yet just type into the console give weapon_physcannon, and the blue gravity gun will be given to you (Just be careful when you aim it at vehicles that aren`t part of the terrain)
