Two new weapons both slot two. Only really useful if your on the back foot and out gunned as if your even you mite as well just shot the lot. This is aimed at a group of light marines.
Tranquiliser: Does limited damage but slows down the attack and movement rate of higher Alien life forms making it easier for them to be killed. The effect should only last a few seconds. Would be ineffective against lower life forms as if you hit it with the Tranquiliser you mite of well have shot them with a real bullet.
Tagging: Does limited damage but high lights the alien on the map and in first person view "paints" them a different colour. This would help light marines concentrate fire on one Ono/fade at a time. Would be ineffective against lower life forms as if you hit it with the Tagging gun you mite of well have shot them with a real bullet.
Alternately you could have just one weapon that has both effects but does no damage.
Possible Limitations to keep balance:
Only one in use at one time (need to have a creative way of explaining this in game).
