Warhammer 40,000: Gladius - Ultima Founding is a turn-based strategy expansion that adds eight new Primaris units to the Space Marines faction in the core 4X game set on the planet Gladius Prime. Players command forces in a hex-based environment where city building, resource gathering, technological research, and tactical combat drive the experience toward planetary dominance.
Gameplay
The core loop centers on expanding settlements across a hex grid while managing resources drawn from terrain features and special sites. Each turn involves moving units, constructing buildings that produce troops or generate income, and advancing through a tech tree that unlocks stronger options over time. Combat resolves on the same hex map with one unit per tile, emphasizing positioning, flanking, and ability timing to overcome enemy formations.
This expansion integrates the new Primaris units directly into Space Marine armies. Primaris Aggressors function as close-quarters anti-infantry specialists equipped with flamestorm gauntlets, capable of anchoring advances or repelling assaults through sustained fire and melee follow-ups. Primaris Hellblasters deliver heavy armor-piercing plasma fire suited to eliminating high-value targets such as large monsters or armored vehicles. Primaris Inceptors use jump packs for rapid strikes, descending to unleash concentrated volleys that disrupt infantry clusters.
Primaris Intercessors provide versatile bolt weapon options for sustained fire during advances or defensive stands. The Primaris Invader ATV serves as a light reconnaissance vehicle armed with an onslaught gatling cannon for quick strikes against weak points in enemy lines. Primaris Repulsor Executioners act as heavy tanks with transport capacity and powerful turret weapons including laser destroyers and macro plasma incinerators. Redemptor Dreadnoughts offer heavily armed walkers that adapt to multiple target types through plasma and other armaments. Storm Speeder Thunderstrikes deliver fast anti-armor strikes by exploiting vulnerabilities in vehicle armor and systems.
These additions introduce fresh tactical choices for Space Marine players, allowing more aggressive spearhead tactics and specialized responses to different enemy compositions without altering the underlying resource and movement systems.
Game Modes
Matches support single-player sessions against AI opponents on customizable maps. Multiplayer options include online PvP battles, LAN PvP, shared or split-screen PvP, online co-op, LAN co-op, and shared or split-screen co-op. Games typically revolve around conquest objectives where factions compete to eliminate rivals and secure control of key locations and resources across the hex grid.
Setup allows adjustments to map size, starting conditions, and opponent difficulty, enabling varied session lengths from shorter skirmishes to extended campaigns of expansion and attrition. The Primaris units integrate into these formats, giving Space Marine commanders additional tools for both offensive pushes and defensive holds in any supported play style.
Faction Enhancements and Mechanics
Space Marines receive the most direct updates through this content, with the eight Primaris units expanding roster depth in infantry, vehicle, and walker categories. Each unit carries distinct roles that complement existing Space Marine strengths in durability and firepower. The mechanics emphasize combined arms approaches where jump pack mobility pairs with heavy armor support and plasma saturation to break stalemates.
Broader faction variety in the base experience includes Orks, Necrons, and Astra Militarum, each with specialized expansion rates, unit production, and combat preferences. The new units maintain balance within the shared combat resolution rules while offering Space Marine players more options for adapting to terrain, enemy types, and late-game threats.
Is It Worth Playing?
Player reception for the expansion stands at Mostly Positive based on recent reviews. It appeals particularly to those who favor the Space Marines faction and seek additional unit variety within the established 4X framework of exploration, city development, and hex combat. The content integrates cleanly into existing single-player and multiplayer sessions without requiring changes to core progression systems.
Those who enjoy methodical turn-based conquest on a contained planetary map, with emphasis on unit specialization and resource efficiency, will find meaningful additions here. The expansion suits players already familiar with the base game who want refined options for one of its signature factions.
