A bunch of new features have been added to Paradox Vector.  Here are some notable ones:

• Antialias Mode - you can set this in the preferences (restart game to activate) and get cleaner lines.   Note, some of the visual effects don't work, so the game will appear darker.  However, it allows more details to be seen, and has helped players who suffer from any dizziness.
• More Environment Art - levels are more distinct now. New trees, creeping vines, industrial scaffolding, pipes and other features now decorate the various locations in the game.
• Bugs Fixed - Several issues have been identified and repaired since the last update.  Areas where you can get stuck in vents and see outside the level, guns that do not appear properly and many other little issues have been resolved.
• Balance - the game has been balanced in many ways in terms  of ammunition amounts and locations.

Realms Deep
Part of this new found interest in the game may be due to the fact that it has been included in the upcoming Realms Deep conference hosted by 3D Realms.  Check out the trailer for this upcoming event!
