Mind control darts would be a side grade for the infiltrator's sniper rifle. They would allow you to take control of an enemy's character for a limited amount of time.
- Doesn't affect MAXs or Vehicles
- Can't enter vehicles
- Can't throw grenades, but can cook them til they explode
- Can't use c4
- Vulnerable while taking control ( + shield loss? )
- Affected enemy can fight movement (similar to jockey in L4D)
- The effect is disabled if the enemy receives enough damage
- May require two darts for effect (first dart slows movement, but wears off if a second dart doesn't hit right away)
The point of this gun is to cause chaos. A sniper could wait for the perfect moment to take control of an enemy and suicide into a group. Or take control of a HA and mow down friendlies. There's an incentive to cause minor damage to a teammate if they're being taken control of to stop the effect, but not so much that you kill them.
The risk/reward for the infiltrator is that they can kill more people per second if they wait for the right moment, but they aren't always guaranteed a kill. Plus it's probably more fun to take control of somebody next to a jump pad, pull the pin on their grenade and launch them like a human firework, than to headshot them.
