Omni mod has some pretty neat features I have listed some of the features but not all of them I think it deserves at least a look. Especially the Anti-Interference With Duels that was Written By Jaii Der Herr and the Jedi Vs Merc Duel.
Jedi Vs Merc Duel
Merc vs Merc Duel
mod_multideploy (allows you to put out more than one sentry
force points increased
Max ammo for all guns increased (hehe 500 sniper ammo is so cool)
clanchat can be used by anyone, but only seen by people who have the same clanpass.
Anti-Interference With Duels, Written By Jaii Der Herr
Players In Duels can not see people outside of the duel.
Players outside of duels can see people outside of the duel.
Players outside of duels cannot interfere with the duel,
as if they walk into the duel they will walk through the duelists
and the duelists will not notice as they can't see anything but the duel.
New Cvar to cause the shields to absorb kick damage (mod_kickshield)
New Saberstyle Icons (Orange looked too much like red. It is now green)
Can Roll/Kick/Wall-Walk while holding a gun
If your intersted into looking at it you can get it here
