Among various aesthetic tweaks, some new features have been added. Importantly, there's now support for projectile physics: anything can fly through the air with a given velocity and angle in 3-space. This will be useful for grenades, severed heads, etc.
The network has also been made robust. A node interface slides out on the top-right when interacting with the network. I'm also putting up a screenshot of a security camera hack in progress:
Ledges now provide cover from bullets and from being seen.
Coming up: RPG-style (starfox style?) communications interface to pop up along the bottom. Hand grenades and secondary-fire grenade launcher for the assault rifle. Smoke grenades / flashbangs?
