How did you separate your team from the opposition? Some glowsticks (think they were glowsticks in the video)?
Yes - with glow sticks
But in a limited area you can mostly gauge who is friendly by where they are in regard to objectives and bases
In the crossing corridors then you can call out around corners (if not worried about giving your presence) or hiding and letting people pass
Familiarity can help when you have an idea on who is on your side by their size and shape eg the idiot with the wings on his back was me, the leader of the Angels
However there are tactics to minimise how obvious you are.
Different glow stick colours have different brightness levels, so to a degree in theory you could get a bit closer and then shoot at the glows if you're on the right faction
A way to reduce that is to spiral some electrical tape around the glow stick (like a barbers pole etc) so that it gives off the glow for ID and the health and safety element of you getting found if you're crashed on the floor in darkness, but reduced in intensity so that you are not such an obvous glow in the darkness
Next depending on your stance put it on the arm that is likely to be behind you, and stick close to walls - then when you're sneaking up in the darkness then your body blocks the glow in front, the wall stops glow from your side (and you're not silhouetted in the middle of the corridor)
with those tactics I was able to edge my way slowly hugging the wall right into enemy hq slowly shuffling forward working out how close I could get and burying my glowstick arm in the wall
You get to a point that you realise there is little you can do but go for glory
And that was when suddenly i was discovered
The photo of my forehead was taken moments later as a selfie to see what all the fuss was about with people staring at me
It grew much bigger!
