Synthesized from 2 Yomimono stories · updated 5d ago

Slitherine published two strategy games in mid-2026. On July 27, the company released the full version of Nightmare Frontier on Steam, completing a year-long early access period for the turn-based strategy sim from Ice Code Games. The Cthulhu horror title blends tactical battles with extraction mechanics and sanity management, and all planned content is now live.

Earlier in June, Slitherine announced that Battleplan, a World War II strategy game from Foolish Mortals Games, would launch on July 14 for PC via Steam, Epic Games Store, and GOG.com. The game focuses on operational planning with a delegation system where players give broad orders and units act autonomously during execution phases. Both titles represent Slitherine's continued output in the strategy genre.
