Be Arnold Schwarzenegger circa 1984 with the weapon types he used to sytematically eliminate possible threats to his kind:

New Weapons:
AMR-18 Rifle with extended 43 round magazine and stock removed.
Spas-12 Twelve Gauge Autoloader
1911 Longslide with laser sighting (second fire button)

Also:
Styer TMP
Crylancer (Automated enegy rifle, secondary for long ranged attacks)

New Buildable:
(for utilitool): Observation Tower (raised tower with 2 stories up top with defensive firing positions)

Fixes:
F3 and respawn are now same amount of time (thus one does not avoid the respawn delay by going to spec and then rejoining)
Proper sound for some weapons. Misc other fixes.
