No More Room in Hell

Initially a mod for Half-Life 2, No More Room in Hell released as a standalone title and quickly garnered praise. The premise sees up to eight players either completing objectives across the map to escape or surviving against waves of zombies while defending different sectors. It’s the combat mechanics that really set it apart – guns and ammo aren’t common so you need to think carefully about shooting (that too without any cross-hairs). No More Room in Hell still holds up despite its age and a sequel is slowly but surely coming along.
