I wouldn't call this something brag-worthy at all unless you count being super sneeky as awesome, but i really want to share this since i don't really see a war story thread right now.
(This post is a direct copypaste from my GameFaqs one, with a few adjustments. The topic is about to get deleted soon so i wanted to save this!)
I had this match during the EU splatfest, team Rock vs. Rock at Bluefin, me wielding Kelp Charger. Right from the start it turned into one of those matches where absolutely nothing went right, with me and my team getting completely steamrolled the first minute in. It was like all of my experience with the charger vanished, i could barely hold a steady aim and i managed to miss every single shot. Me and my poor team got ambushed and splattered with every attempt to take our turf back while they kept going forward to our spawn. They started to make their way up the walls from the center area and kept a iron grip on our space overlooking the central areas, and we barely held them off the grid walkway to our spawn. We were failing hard.
It didn't get better and i realised the match was pretty much done for so i figured screw it, let's see if i can do something. I made my way to the left side of our spawn and took a dive into the orange territory below, and somehow nobody of the entire enemy team present saw me leaping. I charged forward and kept zipping across my charger shots, not looking back and rushing asap across the left center area. I reached their wallside and made my way up there, tossing a sprinkler along the way.
I turned around to see if i could splat any would-be pursuers from a safe distance, but there was absolutely no-one. Just my sprinkler doing it's best and my untouched inktrail. This place was slightly less dead then the rest of my team, who judging from the team status screen were still having a hard time. (And fiy, they didn't even try to superjump at me)
And then, it turned out my team managed to finally splatter three guys. Bad news for me, as this place is going to have hostiles soon. Without thinking, i started inking a path to their side of the walkway, placing a new sprinkler along the way. I went and moved towards their spawn and spotted a guy wielding a Tentatek(I think?) run from enemy spawn, and i charge up my shot and fire...
...And i missed again, meaning the tentatek spotted me and started gunning me down. I charged my second shot to only to hear the dreaded sound of low ink. I fled down the walkway but i was stopped dead in my tracks by another guy who had his back turned to me, busying cleaning up ink that my sprinkler left behind. If i'd step off the walkway he'd surely spot me. And then for no reason, the tentatek ignored me and moved on!
So i got stuck with this surreal image of being completely surrounded by the enemy team, with none of them even noticing me on the walkway! They were all busy cleaning up my inktrails, and i even see one casually firing off an inkstrike. I was stunned, it was allmost as if they accepted me as one of their own. If any of them would've turned around they'd see:
A: Splatoon's worst charger, and
B: A free splat
But that didn't happen, and eventually the guy blocking my path left. I recharged in a really small speck of ink and managed to get my first splat against another guy using an inkstrike! Woo! (While my team did take some turf back, we still lost)
TL;DR : I got surrounded by the enemy team with none of them spotting me
