Cryo-Goo Mines [Lore]:After countless reports of the "Phase shifting demons" being impossible to effectively defend against, the human research division worked day and night to adapt already existing technology into a specialized counter to the Khaara's lightning fast soldiers. Armory-15 Res, 2-3 in a pack. Aliens triggering these mines will be splattered with a quick-freezing liquid agent. Not cold enough to stop the lifeform entirely, the cold causes alien core temperatures to drastically decrease. Immensely reducing metabolism rates for 5-7 seconds. (Reduces energy regen to 0). -Mines trigger instantly and apply to all aliens in a small radius.
Lets marines defend singular locations (bases/strongholds/chokepoints) from fades, without introducing any nerfs, or overwhelming counter mechanics. Leaving fades to prey on silly marines that run off alone (as they should) while encouraging more thought before attacking groups of marines. The energy Regen-prevention is also a soft counter, encouraging teamwork and intelligent placement to actively deter fades from attacking marine strongholds alone, while allowing skilled fades to work around the mechanic and compensate when necessary.
