The Portable Probe Device

When the BioShifter needs to change enemy body, it launches a guided probe on a thin wire. The player will take limited control, turning the probe around corners while inertia carries it forward.

If the BioShifter doesn't control a body while firing the probe, no player energy will be drained.

If the Bioshifter does control a body, control ability (life force, energy) will decrease, so that at launch a 'first shot' amount is deducted, and then more energy drains away while the probe is being controlled.

If the probe hits a body, which is not stunned (and thus unprepared for takeover) the probe will act as a weapon. The target body will lose some life energy and maybe twice the stun energy. So if the probe is being used as a weapon, the result will eventually be a stunned enemy, which has lost a good amount of life energy as well. To the player it will be better to use a dedicated stun weapon, as they don't drain away life energy.

If the probe hits a stunned body, takeover will be almost immediate. The BioShifter will disconnect from the previous body and move along the probe wire to take over the new body.
