[Scrin] Black Hole Generator:
This feature redoes the rift generator into an actual black hole generator. Instead of the Scrin superweapon creating a rift, it creates a black hole in your enemy's base which will never go away. Essentially making where ever you place it no-man's land. It is slightly larger in size than the rift and also requires 15 minutes to be ready as opposed to the regular 10 minutes. If the black hole generator is destroyed a black hole will appear in their base.
[Nod] Realistic Nuclear Missile:
This is an enlargement of the nuclear missile's radius to about 3x times it's current size. Ready time will be 15 minutes as well. If the temple is destroyed a nuclear explosion will occur in your base.
[GDI] Ion Cannon:
Ready time is lowered to 6 minutes.
[GDI] Liquid Tiberium Bomb:
Destroys all tiberium in the map. It's basically a universal catalyst missile. Ready time is 33 minutes. Requires a Space Command Uplink. Destroying it will not induce a liquid tiberium explosion ;D
Narrative Justification:
Tiberium glaciers in the Red Zones have burrowed so deeply into the Earth's crust that their "roots" have come into contact with an as yet unknown element entirely unique to this planet. By fusing with this element, the tiberium in these glaciers have undergone an evolutionary path divergent from the variety used by the Scrin for terraforming, thus making it resistant to the effects of TCMs (Tiberium Catalyst Missiles) and LTBs (Liquid Tiberium Bombs).
