Extreme Justice is for version 1.3 and version 1.4/1.5. It has 7 levels and the file is 9.9MB in size. The file name is extremejustice.zip. It was released on February 7, 2002.

Extreme Justice has good level design and gameplay. There are new textures, weapons, items, and monsters. Health has been increased to 150, and there are new ammo amounts for some weapons. You can climb some ropes/chains and there are nice lightning effects and a cloud path that reminds me of the star walkways in HeXen. It has a fantasy/quest like theme and the only thing that really looks out of place is the weapons. Some of them remind me of the weapons found in the Blake Stone games. I rate it as good with 3 out of 5 stars.
