Starting tips:
After the "accident", you will discover a scientist giving CPR to
a security guard. Wait 15 to 20 seconds to see the outcome, which
usually results in the security guard being revived. He is not
useful at this time, but return to him after getting the crowbar.
Kill him with the crowbar so he can not fire back to get his gun
and ammunition.
Soon after this, you will ride an elevator upward. Have the gun
ready. Shoot the monster attacking the security guard; a couple
of shots should do it. This security guard can cover you until
you reach the main entrance area.
One important tactic in the early game is to use your "allies" to
your advantage. When you no longer require the services of a
security guard, kill him and take his ammunition. A scientist is
also useful in drawing enemy attack. Be careful not to harm an
ally when another security guard is present, as he will attack
you. Also be aware that monsters can sense your allies; and even
if you crawl, monsters can hear your allies' walk.
The beginning of the game also has the following glitch. There is
a scientist sitting in front of a damaged instrument panel, in
the area of the first scientist who opened a door for you. This
scientist is invincible. You can shoot or beat him with a crowbar,
and all he will do is whine. This also saturates the area with a
large amount of blood.
**The following tip submitted by Simon Flavelle ([email protected])
To enable monsters in your maps in a multiplayer games, bring down
the console with the tilde key, then type:
mp_allowmonsters 1
the following will not take effect until you restart the server by typing:
restart
the server will then restart, and the AI bots will be visible in game.
However, in the normal half-life maps, this may only consist of a few
security guards.
