Well it finally happened, the bugs (as far as I know) are gone and I deem the Psionic Storm mutator for UT3 ready for a version 1.0 release. Improving upon the 0.5 beta version is six new moves and some AI improvements as well as the aforementioned bug fixes.
Also out is the full source code for the Psionic Storm mutator and it's underlying architecture (the Impact Extension.) Basically the Impact Extension is a set of things added to UT3 to primarily help developers create content faster and in a more generic way. It is aimed more at mutator developers as it includes the xMutator, which adds extra features to the normal mutator.
The xMutator allows for client side configuration values, HUD management (dynamically placed HUD elements) and player effects (easily added post-processing and such) as well as a host of convenience functions that takes some of the pain out of mutator development. Currently this is only for the PC as, one I can't test it on PS3 and 2 I've heard you can't use packages with mutators, which screws up the whole UI side of things.
The source code is free for anyone to modify and use but I encourage you not to modify and then redistribute the ImpactExtension.u packages as this could stuff up anything that relies on it. Treat it like you would a core UT3 package and code, and if you have any ideas for it I more than welcome them.
Anyway, enough from me, get downloading and blow some stuff up.
