Type:

/spdevmap (name of level)

Then:

/fraglimit 100


This will make the fraglimit increase, so you can play for longer. Remember the space or it won't work.

While playing press ` (Underneath the Escape key) Then type
/god (god mode)
/give all (Get all weapons and items)
/allammo (Get more ammo)

When you enter Quake 3 go to the console

and type devmap and then what map you want to play on.



When it loads,somewhere it must say cheats are enabled.



When you start playing go to the console again and then type ALL of the following text:



give all

give armor

give health

god

give grappling hook

give regeneration

give invisibility

give quad damage

give flight

give battle suit.



If you type in all of these,then you will be invincible!!!



Plus if you type in the same cheat over and over again just by pressing the up arrow key and then enter lots of times then you will have the cheat for a long time,but dont do this with the god cheat because it might not work.
