Partly own, partly loss.
First round on uh, swiftwater I think? We got absolutely demolished on defense, mainly due to a heavy that had a Vaccinator and Kritzkrieg pair of medics stuck up his arse. Points wise, I was the highest on my team with 14 by the end of the five minutes. No one else was >10. By contrast, the entire enemy team had ~25+ points, with the heavy and his twin medics with 51 and 45 each respectively.
However, on offense, things changed dramatically. I swapped from my nade/sticky jumper/skullcutter loadout as Demo to loch/targe/skullcutter. I felt cheesy as fuck resorting to Lochtarge demo, but it's what our team needed. Somehow, some way, i sneak through past the first building near capture point 1, which naturally has a nice little vantage point to the main defense area. Their team is damaged, and clustering around the dispenser while the heavy and his two medics murder our team at spawn. I poke my head out, fire a few Loch pills, take out the sentry. I back off to reload. Their team is still largely clustered, though some have split off to look for whoever just took the sentry out.
I fire three pills at the dispenser from a different vantage point. Four kills. One dispenser kill. Shitloads of damage to the survivors.
This was what our team needed to push through to the first point, finally capping in the last ten seconds. I stand proudly on the cart and laugh at the other team.
Later in the match, I spend a lot of time behind the enemy's defenses taking out engineers and their buildings, and the occasional oblivious sniper. I get divebombed by a soldier or two, but on both occasions i land a pill airshot which at the least scared them off (100 damage + ~15-20 from jump + 25 from landing puts them in a very dangerous spot, with only 200 max hp).
Eventually, we finally push all the way to last, so I keep up my "harass from as far forward as I can, periodically withdrawing to reload and grab ammo while our medic overheals me so I can go back in."
By this stage, I had caught up to the heavy and his medics in points. I spent as much time as I could in the building above the last point taking out sentries and dispensers, of which there were many; they had four engineers with all level 3 sentries up. I could easily pop my head out and destroy one, but by the time i'd backed off to heal and reload, the engi would've respawned and replaced the sentry, while the other three rebuilt the sentry rapidly with their own metal as well. Heck, I even got ubered by the medic on our team to try and coordinate with a spy who'd just sapped the entire enemy nest, but to no avail. By the end of the match, I'd broken my own record for most building destruction in one life, plus gone from 14 points at the start of offense to 78 points, just behind the heavy on 81 and the two medics on about 75 each.
We lost in the end, but damn we pushed back hard after that crushing first round.
TF2, on payload Swiftwater.
