What is Isonzo?

A tactical first-person shooter set on World War I's Italian Front, structured around online battles and single-player bot matches based on historical offensives. Choose one of six classes, attack or defend Alpine positions, or support the team by cutting wire, using heavy weapons, building defenses, and marking targets for artillery or aircraft.

What players say

83% of 17,266 reviews are positive · 80% of 115 in the last 30 days

Players praise the weapon handling, map design, and attention to period weapons and uniforms. The most common complaint is that separate games in the series divide a small online community, leaving some matches reliant on bots. Solo players also criticize bots for limited equipment use and missing officer support.
