Wow, there are some nice ideas in this thread...
But something I need to object to is the idea of mines, landmines, etc... They're already in other free FPS games (Open Arena, Xonotic, etc.) and they mostly suck.
Mines in RE would be a waste IMHO, because you could easily wall-run and impulse dash away from them. Sticky grenades are OK, but an extra weapon for mines, duh!.
Also, to all Medieval haters:
MEDIEVAL & INSTA-MEDIEVAL RULEZ!Splicing someone in half with 1 vertical sword hit gives you such a sense of power

Something I would really like to have is
AKIMBO PISTOLS. You know, the pistol is the only weapon that doesn't get dropped when a player dies, so maybe make it drop and if someone picks the pistol up he gets
dual pistols 
. Furthermore, the Pistol's secondary fire could be used to switch the holding position of the pistols (holding the pistols sideways

).
Also I think the Plasma gun needs a better model. Recently I cut-off my hair, and for some odd reason the plasma gun model looks very similar to a big hair clipper:


The slogan for the next release:
"Red Eclipse, the FPS that cuts your hair with style."
