Spawning NPCs

npc_create <entity name> - Creates the specified entity wherever you are pointing at. Look around for a list of such npcs.
npc_create_equipment <weapon name> - Used in conjuncture with npc_create, you can determine what weapon your spawned npc uses.

Ex. to create a Combine Soldier with an OSIPR you would enter into the console repsectively:

• npc_create_equipment weapon_ar2
• npc_create npc_combine_s

To make this a bit quicker you might do something like this:

• alias spawn_soldier "npc_create_equipment weapon_ar2; npc_create npc_combine_s"
• bind <key> spawn_soldier

which will create a soldier with an OSIPR whenever you press <key>.

Pistol Trick

The "pistol trick" is an exploitation of a bug in the game that allows you to "charge up" any gun without a secondary fire. This allows things such as one shot kills with the USP Match.

-Note- Shortly after its discovery valve released a patch that changed the damage delt by the magnum, changed dm_overwatch and took out the pistol glitch amoung other bug fixes.

To use the pistol trick:

• press and hold the secondary fire button
• while still holding down secondary fire, press and hold the primary fire button
• hold for a period of time
• release the secondary fire

If you did it correctly your gun should fire multiple bullets. The longer you hold down the primary and secondary fire keys, the more bullets your gun should shoot.
