I’ve blazed through NPC Lester Crest’s Grand Theft Auto 5 mission ‘The Construction Assassination’ umpteen times before with a careless volley of ammunition, high-impact firearms and devastating throwables – but this playthrough is different. This rooftop building site is teeming with bad guys. I smile, check the chamber of my trusted Saturday Night Special, and realise I’m out of ammo. He rocks forward, eyes wide, and folds like a deck of cards. 25 bullet splits the goon’s skull with a crunch, and his brains coat the plasterboard wall behind like a Jackson Pollock painting.
