replenish suit energy from dead enemies

[Gleitfrosch]

Dead don't need the energy anymore.

It could be slower than Recharge Sockets and therefore risky in combat but still useful after a combat, especially at POI.

 

[Cliché]

Makes sense. If your suit had a port you could also allow a team mate to get a charge.

It's well known that when you die you release all your battery energy like your bladder and colon.
