There has been updates for two ArenaFPS's this week.
First, Warfork has an update which fixes many issues with the initial release. The main change in this update however was the sounds. For the most part, this was a needed update, though the balance of some of the sounds were off by being either too loud or too soft.
Finally, MFArena also seen a release today, with some minor fixes. While no new maps were added to the game, the “bomb” game type is the biggest update to the game.
