With the 99J3 update out, using the new engine, I'm posting my Shock Indicator Mod.
This places a lightning bolt over a downed body that is losing HP due to overstun. This is for both friends and enemies. Apply stims etc, to remedy this condition and keep them alive.
Note: Dioxine intends to incorporate his own graphic for this in an upcoming version, so this mod would not be strictly necessary but be an alternative.
