This game seems to have spiked in popularity recently. I picked it up and I'm quite enjoying it.

I don't see a lot of model replacement packs (or any for characters?) on the workshop, but it appears you could. The workshop section on "Total Conversions" seems really thin, so here's a couple suggestions.

I do game dev for a living, so I don't really have time to make mods, but I thought I'd throw a couple ideas out there.

Just some ideas, fairly simple too:

Star Wars total conversion:
- Stormtrooper (various types?) model and sound replacement pack for Security
- Rebel Alliance models and sound replacement packs for insurgents. (Maybe Endor?) Perhaps one could go ahead and just use the Security voices for the Rebels.
- Weapon packs replacing the existing weapons with the various weaponry of the Star Wars universe. I guess you wouldn't have to worry about bullet travel time. Not sure if you could force 'tracers' (red) and replace the graphics to make them look like blasters.

Halo Conversions:
- ODSTs or Spartans as Security. No shields, of course. Probably wouldn't have to replace sounds.
- Insurgents actually wouldn't have to change at all. In Halo lore, ODSTs are originally deployed on planets to quell rebel uprisings and things of that nature.
- Weapon packs to replace current guns with all the various human weaponry from Halo.

Looking at all the mods for L4D2 and things like that (running on Source), I'm a bit surprised no one has done this already, which makes me think there could be some underlying issue as to why no one has created very many model replacements yet.

Star Wars and Halo as tactical shooters? I would pay for that sort of game it sounds so good.

Anyway, just some fun ideas to think about.
