7 Days to Die

The Fun Pimps call 7 Days to Die a combination of first-person shooter, survival horror, tower defence and RPG, and the feature list is all four. Five biomes, a fully destructible world, and forts you fit with traps, electric power and auto turrets. Structural stability is real, so a badly designed base collapses under its own weight. Recipes are learned from schematics, and perks sit under five attributes topped up by over a hundred books. Traders buy, sell and hand out quests, and nearly sixty zombie archetypes escalate against whatever you have built.
