Like Halo CE PC, this game is considered abandonware and as such you can't find it on steam.
The best place to download the game is from Project Cartographer ([Link])
Click on the top download button to get the game (Full Game Installer + Mod)

Here's the table.
-Shield/Health Lock
-One Hit Kill
-Stealth
-Ammo Lock
-Grenade Lock
-No Shield Recharge Delay
-No Damage Indicator
-Values
-EXTREME GAMEPLAY (LEGENDARY++)
(UPDATE) The stealth should disable when the cheat is disabled, so you don't have to do that bit of funkiness from the original cheat. Also Grenade Lock will reset grenade values to 4 if the cheat is activated while you have no grenades.
(UPDATE 2) Health Lock will now be disabled while EXTREME GAMEPLAY is active.
How to use this cheat table?
- Install Cheat Engine
- Double-click the .CT file in order to open it.
- Click the PC icon in Cheat Engine in order to select the game process.
- Keep the list.
- Activate the trainer options by checking boxes or setting values from 0 to 1
