Natural Selection 2 is the sequel to the popular Half-Life mod Natural Selection. It is built on our own engine and will be distributed through Valve's Steam platform.
The Crag fills the role of the Defensive Chambers, from NS1, providing Commander-researched, player-purchased, defensive-oriented upgrades. For example, Carapace (late game armor) and Feed for Skulks (health for eating corpses) and Bacteria for Gorges (upgraded health spray). The Crag’s bony shell helps serve as natural protection, making it one of the toughest alien structures to kill.
Unsurprisingly, the Crag's passive ability is Heal. It automatically heals nearby alien players and structures, ala the old DCs from NS1. Its Triggerable ability is Umbra (sound familiar?), which when activated by the commander, creates a particulate cloud of gaseous smoke which pours from the holes in its shell, and fills up the surrounding area. This temporary cloud intercepts and disintegrates bullets, allowing through only half of the shots fired by Marine ballistic weapons (doesn't affect flamethrowers, grenades, MASCs).
The Crag's late-game "targeted" ability is...Babblers! If you played early versions of NS1, you may remember this fun but unrefined feature that allowed Gorges to spew out small creatures (they were scaled down Skulks running the Half-life Snark code!). Well, we are bringing those back, but making sure to give them their own model this time around. In NS2 they are controlled by the alien commander, who will unleash a multitude of these small cat sized critters from the various openings in the Crag’s shell which swarm around Marines, obscuring their sight somewhat, slowing them down and inflicting a small amount of damage.
very well done
