Warhammer 40,000: Gladius - Onslaught Pack
Eight new units for Gladius Prime, but this DLC pack only clicks if you already own the base game and crave fresh tactical variety.
GamerScout Verdict
Tactical variety boost for existing Gladius players, but thin value proposition for newcomers.

About Warhammer 40,000: Gladius - Onslaught Pack
I picked up the Onslaught Pack expecting a meaningful strategic refresh for Warhammer 40K: Gladius, and what's here is functional but narrow. The eight new units genuinely do unlock fresh build paths and force you to recalculate your opening engagements, which matters in a tactics game where unit synergy drives 80 percent of your decision-making. The problem is scope: this isn't a campaign expansion or a new faction with asymmetric mechanics. It's eight units, dropped into existing armies, which means you're paying for incremental roster bloat rather than a structural overhaul. Worth it only if you've logged serious hours in Gladius and want to break habitual army compositions. Otherwise, wait for a deeper expansion or grab the base game at a discount first. The tactical layer is there, but the value proposition here is thin.
