Oh, yeah, I had fun today defending the intel as a Demoman earlier. Couple of Engineers had the one entrance blocked off in two directions with their Sentry turrets, so all I had to worry about coming from their end was a cloaked Spy, so I just had to park my back in a corner and watch the other way with my Scottish Resistance stickies littering the floor.
Turns out one spy managed to make it by a few times, and he would try to tangle with me because he couldn't clear out enough of my stickies without me noticing them disappearing and blowing the rest of them up in his face (they were seriously scattered around) and charging him with my regular launcher/whiskey bottle, or risk trying to pick up the intel and run by without his disguise, prompting me to gib him with the mines.
Ended up dragging him down below-decks (this was on 2fort, I know, we all agreed it's a terrible map but I still enjoy it) and murdering him a few times, and then he started getting smart about it; he realized I'd run up to the courtyard every so often to help the engineers up there deal with the Heavy+Medic, Pyro, Demoman, Scouts that would come runnin in and try to pick off their turrets (and I scored a fair amount of kills by lobbing grenades under their cover from the shed in the courtyard, wheee) that he'd wait for me to come back down and try to backstab me as I went into the resupply room.
The first time I went down I discovered he was smart to me because I was backpedaling down the stairs, shooting my grenades up, and he tried to get between me and the resupply so he could stab me - but I whirled around as I shot my last grenade to reload and steer myself better and saw him decloaking. Loaded a grenade, snap-shot it at him, missed but it bounced around and dealt some splash damage, I swapped to my bottle and ran into the resupply, then turned around and blew my SR stickies under him. Gibbed!
Later on I acted as though I was gonna run for the ammo and health kits down there, stopped and whirled and shot a pair of grenades in one smooth motion and killed him, cuz he was moving in directly behind me.
Another time I'd accidentally hurt myself a bit with a richochet'd regular grenade to my face, and went to go pick up the health kit, but it wasn't there cuz I'd just ...done the same thing a few moments earlier :>
and bumped into him. He'd taken a few shots while running down the spiral, and was waiting for the health kit to respawn under him. Kerplooey!
:3 I had fun playing defensive Demo~
