Just FYI, MekTek's MP4 is supposed to have free-reticle aiming enabled, last I heard. The last posts I saw on their website indicate release after the upcoming AT1 beta release. That of course says nothing about *when*, other than the patented SOON4, lol. Hopefully this year.
Once again, FYI, everything MekTek does is reverse engineered on top of MW4 Mercs. They don't have the source, they don't have the SDK (tain't one). The game engine is 8 years old I think...this is their last release on that engine - that's why they are moving to AT1, I think. AT1 is built from scratch using a game engine of their choice...I haven't been following that build, so I don't know much about it.
