Act of War: High Treason, developed by Eugen Systems and published by THQ Nordic, is an expansion that builds upon the modern warfare framework of its predecessor while attempting to broaden both its scale and tactical depth. Set within a tense, techno-thriller narrative involving political conspiracies and global instability, the game continues its story with a tone that blends military realism with cinematic ambition. It doesn’t reinvent the formula, but it refines and expands it in ways that make the overall experience feel more complete and strategically layered. At its foundation, the gameplay remains rooted in classic real-time strategy design. Players gather resources, construct bases, and deploy a wide range of military units, from infantry and armored vehicles to aircraft. What distinguishes High Treason is its effort to push beyond purely land-based warfare. The introduction of naval units adds a new dimension to battles, forcing players to consider additional fronts and rethink how they approach engagements. Combined with the inclusion of mercenary forces, which provide specialized units outside of standard faction rosters, the game offers more flexibility in how players build and execute their strategies. The campaign is one of the game’s strongest elements, offering a variety of mission types that go beyond the usual “build and destroy” structure. Some scenarios emphasize defense under pressure, others require careful tactical positioning or limited-resource management, and a few lean into more scripted, narrative-driven objectives. This diversity keeps the experience engaging and prevents it from settling into a predictable rhythm. At the same time, the challenge level can spike unexpectedly, with certain missions demanding precise execution and quick adaptation. While this adds tension, it can also lead to frustration, particularly for players unprepared for the sudden increase in difficulty. Strategically, the game encourages a balanced approach to combat. Success often depends on effectively combining different unit types rather than relying on brute force. Infantry, vehicles, and air support each play distinct roles, and understanding how they interact becomes essential as the campaign progresses. While the factions themselves are not drastically different in design, they offer enough variation to keep gameplay from feeling overly repetitive. The systems are familiar to RTS veterans, but they are implemented with enough care to remain engaging throughout. The narrative continues the series’ focus on high-stakes political drama, delivering a story filled with intrigue and shifting alliances. However, its presentation lacks some of the distinctiveness that made the original game stand out. The reduction of live-action cutscenes in favor of more conventional storytelling methods diminishes some of the cinematic flair, making the narrative feel less immersive despite its ambitious scope. The story itself remains compelling, but its delivery doesn’t always match its potential. Visually, the game performs well within the context of its time, offering detailed environments and satisfying visual effects that bring large-scale battles to life. Explosions, unit animations, and environmental destruction contribute to a sense of intensity, even if character models and finer details show their age. The audio design complements the action with solid effects and a fittingly dramatic tone, reinforcing the atmosphere of modern warfare. There are, however, some limitations that prevent the game from fully realizing its ambitions. Technical issues such as occasional bugs and performance inconsistencies can interrupt the flow of gameplay. Additionally, while the expansion introduces new features, the core experience remains closely tied to the original, which may leave some players wishing for more significant innovation. It feels more like a refinement than a transformation. Even with these shortcomings, Act of War: High Treason stands as a strong entry in the real-time strategy genre. It offers a satisfying blend of tactical depth, varied mission design, and narrative ambition, making it a worthwhile experience for fans of modern military RTS games. Its improvements over the base game are meaningful enough to justify its place, even if it doesn’t radically change the formula. Rating: 8/10

I first played this back during my collage days when it came out. One if the few games where naval ships are seen as massive. Also, a fun game to play.
