This week in PC games: a human-eating Katamari from outer space, Planet Zoo 2 nature reserves, and Napoleonic body horror in Valor Mortis

This week's PC games roundup includes Planet Zoo 2, which lets players run a nature reserve and build aquariums and aviaries, and Rolla, which casts players as a malevolent human-eating ball of tentacles rolling through a city like a Katamari. Valor Mortis is a first-person soulslike set in the Napoleonic era with body horror, and Total War: Shogun 2 - Compete is a remaster with fancier graphics and 50 new minor factions.
