So, you've beaten Unreal II and want more gameplay out of it, or maybe you just want to mess around with it anyway.

Here's how.

First, start the game. It doesn't matter if you make a new game or load a save or whatever.

Press the ~ button on your keyboard once you are in game, and type 'bemymonkey' without quotations to enable the ability to use cheats. Now for the codes!

Here are some codes for your enjoyment.

I am formatting it like this.

(Code) | (What it does)

__________________

Bemymonkey | Enable Cheats
Ghost | Noclip
God | Godmode
Goodies 0 100 | All weapons/ammo
Sum (spawn code without these parenthesis) | Spawns items/characters
Behindview | Third Person
Fly | Fly without noclipping
Walk | Disables fly or noclip.
togglespeed | Multiplies speed by two. Use it again to return speed to normal.
PO | Disables AI and door animations (you can still walk through doors though), type again to enable
Toggleinfiniteammo | Toggles infinite ammo
Togglereloads | Toggles the need to reload
Toggleinvisibility | Toggles whether or not AI can see you.
Allammo | Max ammo.
Open (Map name) | Select Level
Next Level | Go to the next level.
Teleport | Teleport to the location you are looking at.


Now onto the codes you can use with sum:

Here are the codes you can use with sum. The format you would type it in console is as follows, for example:

sum u2pawns.u2izarian

that will spawn an izarian infront of you.
