Old Skool Monsta Toolz (OSMT) is a toolset for UT2004 that is designed to reintroduce 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. It also includes a new story-driven singleplayer or cooperative gametype (OSM Adventure) with
progressive objectives conquering puzzles, traps and monsters.
The only real forseeable problem with this update is that it conflicts with the Invasion AI, and therefore is not compatible with that specific gametype.
The v1.4 update adds a new ScriptedAction command, ACTION_SetEnemy, which can be used to force-select a specific monster's opponent. It also fixes the options display for OSM Adventure Server Rules and patches a small bug which caused the Brute to play sleeping sounds whether it was asleep or not.
