Gladius refuses to die quietly. Seven years after launch, Proxy Studios has added another content drop to its long-running 4X strategy game. The Onslaught Pack is a small unit-focused expansion, bringing ten new units, one for each faction into the game. There are no new mechanics, no new factions, no campaign content. This is a targeted update for players who know exactly what they’re doing.
Each unit is designed to fill a gap or expand a tactical option. Some push harder into late-game power spikes. Others offer utility or counters to existing threats. These aren’t reskins or stat tweaks. Each model has its own design, rules, and place on the battlefield. Several bring new abilities that force a rethink in faction matchups. The focus here is not balance. The pack exists to escalate the conflict.
Highlights include the Space Marine Inceptor Squad, which brings jump-pack mobility and plasma aggression in one fast-moving unit. Necrons receive the Canoptek Acanthrites, fast skimmer attackers with armour-piercing capabilities. The Astra Militarum get the Sentinel, finally giving them a cheaper scouting option with decent firepower. Tyranids gain the Biovore, with indirect artillery that adds pressure without full commitment. The rest of the roster fills in similarly, with each faction getting a piece that shifts their play slightly off-centre.
There’s no grand reveal or lore framework wrapped around this release. The Onslaught Pack is functional. It’s content aimed at players still active in the multiplayer and AI skirmish scenes. It gives modders more variables, long-time players more tactical depth, and competitive fans another layer to exploit.
As with all Gladius content, the pack integrates cleanly. AI factions use the new units appropriately, and there are no major balance concerns so far. Proxy Studios continues to handle integration better than most. The game remains stable, and its systems still hold up under pressure.
There’s no indication this is the final DLC, but it feels like the tail end of the development cycle. Gladius has outlived expectations. Its post-launch support has been consistent, focused, and relatively modest in scale. The Onslaught Pack keeps that pattern going. It doesn’t shout. It reinforces.
For players still grinding out glacial, unforgiving matches in the deserts of Gladius Prime, it’s another toolset. For everyone else, it’s a reminder that sometimes, even in 4X games, war never truly ends.
