One of the sweetest Co-op games ever made in my opinion. 
by jom_yong » Sun Aug 10, 2014 12:09 am perk effects/weapons: (basic overview)
red lightsaber (must be fairly powerful)
dual wielded red lightsabers
double bladed lightsaber (stronger like dual wielded lightsabers but with greater reach)
force powers; force push and pull (reskinned zero point field manipulator as used by sentry tech {reskinning idea by Jelinator} force push may do additional damage as opposed to only pushing away zeds), force choke (hold in air or ground while doing gradual damage, idea by Silent_Ranger}), force lightning that stuns and does some damage (only sith lords can use lightning with the exception of one jedi but whatevs, lightning effect as used by lightning bugs and shocktrooper perks), force wave (more powerful version of force push, does area damage and will be modified siren scream with pushing effect, added damage like force push but stronger and without siren scream sound), force lightning wave (as seen in Force Unleashed, combination of force wave and lightning), force speed as a burst of speed, if possible some force abilities can be secondary fire mode of the lightsaber (but could interfere with reskinning zero point field manipulator, not sure) or could just be modded as separate weapons,
and perhaps other force powers as are suggested
minimal armor as sith lords do not have any (unless added at a very high level to mimic Darth Vader's armor) and significant weakness to bloat bile, fire, lightning, etc
extra movement speed as force abilities allow (could replace or be replaced by force speed or simply complement it)
higher jump, maybe the moonbase jump effect
and whatever else can be thought of
Jelinator also suggested a Halo ODST perk with a weapons from a variety of categories like ARs, SMGs, shotguns, rocket launchers, perhaps with some silenced weapons as well, also minimal armor as ODSTs do not have energy shields unlike spartans, slow to moderate movement speed as the # of weapons would be great
basically a perk with a wide variety of weapons but balanced with slower movement speed and whatever other vulnerabilities
