The new version is out (v1.2.2) an it 0wns.
unfortunatel the readme is not complete, but here is the complete version changes:
*Made it so when u die with an Adrenaline Power up,
the remaining 'Adrenaline points' are not lost
*Replaced the 'Minigun' with a 'Spas Shotgun'
*Fixed the 'Heavy Machinegun' Skin.
*Made it compatable with the Epic Bonus Pack
*Replaced the 'Health Vials' with 'Mini-Shields'
*Replaced the 'Mossberg Blade' with Slugs
*Replaced the Nuker with the Grenade Launcher
*Added the 'MT29' Arena Mutator
*Powered-up the 'Riot Disc' a little
*Replaced 'NUKER' and 'Noggin Gun' with a two Grenade
*Powered-down the Mossberg
*Powered-up all the non-shotguns (Xcept for the M16)
*Changed the Death lines and Pickup messages
*'Wall-Sparks' is a new feature of Stratus. When you
shoot a bullet, Instead of the bullet being instant-
hit, the bullets are slightly slower, so players
must aim ahead of the target slightly.
The other part of 'Wall-Sparks' is that when a bullet
hits a wall, instead of thudding into it, the bullet
sprays out flak, gravel, dirt etc which harm the
player, much like real life (I think).
This has some added bonuses, players cannot run
up to you and shoot, because the flak will damage
them too. Also if a n00b or otherwise runs behind a
pole and you cannot see him/her, then using 'Wall
Sparks' you can shoot next to where they are hiding,
and damage them.
