Which in-game non-verbal communication do you use?

I sometimes tried to shake my (bot's) head in front of a camper blue, not sure how it will look to them ...

and this was to a red bot: met a red natasha busy shooting zenit / noricums on SF. I (was in a rog) stopped right in front of him and just looked at him for 10 sec. took a photo and went on my way towards a nearby beacon. not sure what communication he rceived, but he tried to move away from me

I've used the following, but as a player who has never used voice comms and doesn't squad much I'm also interested to learn of other non-verbal communications others use to support team play.

Head-shake: rotating your head/turret left and right like saying "no". Usually to indicate displeasure or disappointment with another bot, especially if they are using a really bad build or obviously joke/tank bot (no weapons, all Nori's, etc)

"The Stare": walking past a bot but tracking it in view even as I walk away. Again, usually to show displeasure or communicate that something they are doing or the build they are using is sub-optimal.

Instructive/directional shooting: shooting a teammate to get their attention then shooting in another direction after they look at you. Intended to direct them to a beacon they should go get or indicate a flanking direction they should take to support a push.

Spinning discharge: usually after a win that goes down to the wire to celebrate. Shoot all weapons and spin your turret after the last red mech out. Should be used sparingly to avoid being a poor sport or bad winner.

Goosing: running your bot into a teammate, usually to get their attention. Best with a small bot that can lift them up as it gets maximum attention.

Obstructive shooting: only in cases when a red is creeping up on a flank or rear and the blue next to you is unaware and firing on another, lower priority red. I shoot the creeper and move laterally in front of my teammate line of fire to both maintain suppressing fire and call out the approach to my fellow blue.

On your left: shooting 1-2 blasts from a single weapon to either side of a blue in front of me to let them know I'm trailing or about to pass. Especially good in a faster bot (ex: a Rhino in assault mode) when going up a ramp to let my mate know to move over and that I'm coming with - or to slow down so we can approach together. Also used if I have a shield bot and my mate is in a plasma-vulnerable bot like a Carnage - a heads up to get behind me and save HP so we can double up on an attack.

Edit: forgot one - the "come on": if a heavy lumbers to a far beacon and I pass them with a light bot as they get close. I'll stop outside the beacon ring, look back at them and wait (or make small circles while looking at them). Intended to communicate that I'll wait for them so we can both get the beacon together. Need to reward the big fellas when they make the effort - but within reason. Mainly do it if they were halfway there before I raced over. If I headed there first and it would take 10+ seconds for them to catch up I'll usually just grab the beacon so they know to skip the walk.

This is one of only two in game non verbal communications I use with fellow blues.

The other one is doggy style. It means I am going where you are going and yes, you are the initial meatshield, congratulations you lucky dog.

good thread. I use many of the above but here is one. during the past event, using a gala or gareth while on the beacon task I approached a beacon where there is a red and push the other bot off the beacon area. Didn't shoot while they generally shot at first. once the red is off I stand in the beacon area and once it turned blue I move off. 9 times out of 10 the massage gets through and its a beacon fest there after.

It's funny coz it's true ?

Ever had an argument with a blue? A Carnage wanted to go to the right (in a hurry), I wanted to go to the left (in a hurry) and we ended up doing a weird tango and going nowhere.  So he shot me in the face, so I shot him in the belly....

This ranks right up there with someone not knowing how to circle dance with a team mate. They want to line dance instead and end up pushing you out into harms way just so they can shoot at my 320m target ineffectivly with their orkans whilst simultaneously pushing me out into the harms way I was trying to escape. 

Then I die, then they die, then I avoid them the rest of the match.

I shoot the guy to get his attention, then run toward my destination while facing toward where I want him to go and firing a single weapon slowly toward where I want him to go - people seem to get this at least half the time.

Pretty often you don't know where they are heading until it's too late :( 

Oh, and there is a tip too.
Pretty often guy with the Taran shooting at some wall is doing that ONLY to empty the clip so he enters battle with full load.

Layman's terms: stop looking at me when I'm shooting a wall with Tarans! :-D

I use the middle finger or grab crotch and thrust hips forward move to communicate with team members. It doesn't work but at least it relieves some tension during the game.
