Old school TBS, post-apoc survival and RPG. Recruit deranged locals in your militia, ally local factions and fight those you hate. Haul loot back and rebuild your shelter, doctor your wounds, and fix your guns. People need feeding, booze needs brewing and there is an end of the world to enjoy.
Zemalf knows his turn-based strategy. He's so good, PC Gamer wrote an entire article about his feats in XCOM ( https://www.pcgamer.com/worlds-best-xcom-player-how-zemalf-beat-enemy-within-on-impossible-ironman-with-zero-deaths/ ).
Did he manage to survive the zombie hordes in Urban Strife? You can check his first encounter with the undead in this re-run of the 6 hours stream he did back in December. We know it's an older build, but the combat is as visceral as ever.
