The demo could be longer, as always… but I’d say it’s almost certainly wallhack. There are moments where his preaim could be explained by him knowing the locations the enemies are most likely to appear (windows are kinda notorious for not moving around much:-P), but from about 5:55 onwards he starts doing pretty funny stuff, attempting to shoot at the invisible enemy climbing up the ladder in the garden, and shooting through a teammate at an enemy he shouldn’t see. (There are also those glances through the floor.)
