UT2k4 RPG

I saw this mutator running on some random servers in the server list way back when, and forgot about it until recently.  Then I googled it up and installed it.

It's pretty neat.  For each kill you get while you have it loaded, you gain experience.  When you get enough you level up and get points that you can use to make your stats better.  Stats include things like weapon damage, damage reduction, health capacity, adrenaline capacity, and ammo capacity.  You can also save up the points to purchase various passive skills that do things like increase the distance you can fall before taking fall damage or periodically giving you adrenaline.

Beyond the stats, it also adds random modifiers to the weapons you pick up.  There are prefixes and suffixes as well as plus bonuses that increase the damage you deal with that specific weapon.  One of the best suffixes is "of Infinity", which gives the weapon infinite ammo.  Get a Minigun of Infinity and you're good to go, though my personal favorite is the Flak Cannon of Infinity.  The Redeemer or Ion Painter would be interesting to have "of Infinity" on as well.

There are also artifacts, which are similar to relics but are only active when you enable them and consume adrenaline when used.  My favorite of these is the Summoning Charm, which takes a random amount of adrenaline and then according to the amount it took summons a friendly Invasion monster of appropriate strength (i.e. the more adrenaline it takes, the stronger the monster it summons).

Funny I should mention Invasion, because UT2k4 RPG and Invasion seem to be a match made in heaven.  I guess it's just the whole "killing monsters" aspect of it, but it just feels right.

Segueing into Invasion, DM-KillbillyBarn is an awesome level for it.  It's not very big but it's very open and if you grab the Ion Painter off of the top of the silo you can pwn things from the roof of the barn.  It also has some extra sound effects, so when you pick up the damage amplifier it goes "YEEEEEEEEEEHAAAAAAAAW!", when you walk up to the front of the truck it honks a Dixie horn at you, and there's a radio in the barn that if you stand near it you can hear a radio broadcast.  Oh and there's a barking dog tied to a tree.
