The Red Line is a serious game about deterrence in the long pre-war. Playing a national leader facing a rival power, you draw red lines, send costly signals, and manage the domestic audience costs of backing down or escalating, all while the security dilemma pushes both sides toward confrontation.
Every decision is resolved deterministically, and a debrief with counterfactuals shows how a different signal might have changed the rival's read of your credibility. Built for military professionals and national-security enthusiasts.
