Left 4 Dead was one of those games that cast a new mould that many would copy and fewer still would truly improve on. The four-player co-op genre nowadays has people hunting down everything from ghosts to robots (the very excellent G.T.F.O. and Phasmophobia come to mind) but there will always be a special place in the heart of every gamer lucky enough to be there for L4D in its prime.
