Doom 64 Cheats (Nintendo 64)

Enter W93M 7H2O BCYO PSVB. This code will give you 100 health, 200 armour, all weapons,
full ammo and a backpack. It'll also supply you with the three pentagram icons that make
your laser three times stronger than the BFG and can kill bosses in four seconds flat.
These useful pentagrams also let you use the three mysterious switches in the last level,
closing the gates which spawn the monsters.

In Doom 64, enter this password ?TJL-BDFW-BFGV-JVVB. At any time during a level, pause it
and there will be a new option called FEATURES. IT will give things like invincibility,
all weapons, etc. In the first feature choose the level you want and press a C button to
go to it.
