Another idea I had just now was to give humanity a ranged stun weapon.
It was kind of dumb that all we had was a cattle prod literally starting out; and we had to reverse engineer SMALL LAUNCHER to get the capability to stun from a distance.
BZ Gas --In small doses, this makes you stupid, literally. You take your clothes off and mumble incoherently. At higher doses, you get knocked unconscious.
Kolokol-1 Agent -- Kolokol-1 takes effect within one to three seconds, rendering the subject unconscious for two to six hours. Kills a certain amount of people anyway.
So how about this for human ranged stun weapons:
* Proximity Gas Grenade. (there were actually special VX Nerve Gas landmines made in the Cold War and stockpiled).
* Gas Grenade.
* Heavy Cannon -- Reworked to to be conceptually like a 40mm grenade launcher. Very inaccurate, due to the need for low recoil as it's hand held. But since it's now a 40mm grenade launcher, you could have it fire a whole range of payload grenades:
--Explosive Grenades
--Proximity Grenades
--Gas Grenades
--Bean Bag Rounds (Ow, what just hit me?
)
--Conventional Flare Grenade (a lot more light than electro flare, but can set something on fire)
--Electro-Flare Grenade (less light than electroflare, but won't set an area on fire)
The gas weapons that humanity has at the start of the game are a mix of BZ and Kolokol-1 in effects.
Aliens have about say 15-20% chance of being affected by it during each game turn. Humans, 90%.
You roll to see if the unit is affected, then proceed to the random choice table:
*Unit becomes disoriented. They walk off into a random nonsensical direction. They drop their equipment at random.
*Unit takes stun damage.
*Unit takes health damage.
So basically, the aliens still retain a solid advantage with their Small Launchers, as they inflict massive stun damage in one turn; and are 100% safe.
Human ranged stun (at least in the early game) should be unreliable and dangerous.
Mutons could be totally unaffected by early human gas grenades.
You could find an Ethereal commander and try to stun him with a gas grenade, only to find that he had an adverse reaction to the BZ/Kolokol-1 and died. Likewise, you could toss a gas grenade into a convience store to knock out some sectoids, and instead end up killing a bunch of civilians.
Whoops.
