Old Skool Monsta Toolz (OSMT) is a mod/add-on for UT2004 that is designed to reintroduce the complex old skool Unreal monster AI and it's related actors for use in any gametype. These tools mimic the original Unreal actors and settings so that "old timers" can easily pick it up and "newcomers" have lots of online reference documentation already available.

The toolset also includes a new gametype, OSM Adventure (OSM), which makes use of all classes in the toolset to facilitate story-driven adventures through progressive Objectives comprised of puzzles, traps and monsters.


The project's aim is to allow the vast community of UT2004 mappers to create maps that take advantage of this well-designed AI scheme in any gametype, especially in story-driven SinglePlayer and CoOperative adventures. This even allows aspiring game designers to easily develop whole game prototypes within the UT2004 framework, by providing a foundation of code to expand upon which frees them to concentrate on gameplay and art assets.


For mappers of UT2004, this is a set of tools that you can use to implement very complex monster/NPC behavior in any gametype. For players, OSMT is a small download that allows you to play a wide variety of maps in any gametype that include monsters/NPCs with advanced AI. OSMT also includes a new Single Player / CoOperative gametype, OSM Adventure (OSM), with progressive objectives conquering puzzles, traps and monsters. OSM Adventure maps, are primarily story-driven adventures that range from sci-fi to fantasy to purely arcade, however completely different kinds of games, such as driving games, platformers, mysteries, etc., can be made with OSM Adventure as a base.

I was invited to AISD and saw their Game Prototyping class final projects; half of which used OSMT. This project was made to help game designers in this way. Glad to see it put to use.

(Under construction. Actually, just getting permission to link to various groups.)

    Old Skool Monsta Toolz v1.53 can be downloaded from ModDB here: LINK

    Old Skool Monsta Toolz v1.53 Final Release

    Highlights include:

    • Camera shakes from damage and blood splatters from melee damage in OSM Adventure
    • OSM Populate mutator populates any map with creatures, advanced options include settings for which creatures (even characters), and can end the map when creatures are all killed (Not for use with OSM maps; DM maps are great for this though)
    • Warlords can use tactical teleporting for hunting, evading, and even leaving the map altogether if defeated
    • ShieldGun, Translocator and Flashlight pickups
    • Vastly improved creature combat behavior and improved creature team behavior for higher intelligence creatures

    This is the final version. There are a number of additions and fixes to this version, although be aware that some are included as-is, some in a working development state. That means some of the working features may not function under certain conditions, or they may actually be disabled. But, the 'done' and 'testing' items should be fully playable and functional.

    Thank you to all who have supported this project over the years. The hope is that everyone can enjoy mapping, modding and playing UT2004 with puzzles, traps and monsters!

    I just tried OSM-Gauntlet with the latest version, and the enemies will often just sit around and look at me instead of attacking or dodging. It mostly happened with the Skaarj, Krall, and Pupae. The flies and Gasbags worked perfectly, though.

    It's really good to see that UT2004 is still getting useful mapping tools like this. Thanks for the final release, SuperApe!

    Downloaded the mod and am getting ready to try it. I believe this is the one ingredient that I am missing for the DW Monster Evolution game.

    Hi Super Ape, i was wondering if you could make a version of the velociraptor for your mod.

    I would like to add raptors to my mod... one of the maps is in the dino era, and they would go very nicely there.

    Hit me back here:
