Onslaught

Lore & Background

In the competitive circuit of the Unreal Tournament universe, athletes are tested not only on reflexes and weapon mastery but on their ability to hold a line under sustained pressure. Onslaught is the mode that isolates that second skill. Each team is granted a central base—a hardened structure with a regenerating shield and a finite health pool—and the match is won by the squad that chips through the enemy's defenses first. The credit system transforms every engagement into an economic decision. A well-timed kill feeds the team's war chest; a bot destroyed in the enemy's yard is a small but vital investment. Control points scattered across the map act as steady income streams, rewarding teams that can project power across the arena while still keeping their own perimeter secure. The tension between committing players to an assault and leaving the base undefended is the mode's central drama. Across the series, the base has evolved from a simple destructible object into a layered structure with shield, health, and multiple turret slots. The turret types—rocket, flak, arc, and others—give defensive players a toolkit that can reshape the flow of a match, turning a losing team into a fortified garrison or an advancing squad into a wall of automated fire.

In Their Own Story

The arena hums with the low thrum of the base shield. Red's point man crouches behind a crate, watching the enemy's third wave peel off toward the control point. He taps the comms: two on turret, one holding the flank, the rest pushing. The blue team's rocket turret spits a streak of orange across the corridor, catching a runner mid-stride. Credits tick up on the HUD. The base shield flickers, holds, regenerates. Somewhere behind the smoke, a flak turret locks on and the sky over the enemy yard blooms with shrapnel. The base health bar drops another sliver. Red's commander exhales, reloads, and moves forward. The match isn't over. It's never over until the shield shatters and the core cracks open like a geode.

Objective: Two teams fight to destroy the enemy's central base, which has both a shield layer and an underlying health pool. The match ends when one base is destroyed. Economy: Players earn credits through enemy kills, destroying enemy bots, and holding control points on the map. Credits are a team resource used to purchase weapons, build turrets at the friendly base, and repair base health. This creates a constant tension: spend credits now for an immediate advantage, or save for a critical turret or repair later. Turrets: The base provides multiple mounting slots. Common turret types include rocket (direct damage), flak (area denial), and arc (electric chain damage). Turrets are automated and persist until destroyed by the enemy, making them a long-term defensive investment. Ideal maps: Open arenas with multiple lanes, central control points, and clear sightlines to the enemy base. Maps that allow flanking routes while keeping the base approachable reward both aggressive and defensive play. Evolution: UT99 (1999) introduced the core loop. UT2003 refined base sizes and turret options. UT2004 expanded turret variety and shield mechanics. UT3 (2011) streamlined the economy and base presentation. Competitive use: Onslaught rewards role specialization—dedicated turret operators, economy managers who focus on bot kills, and assault players who push the enemy base. Rocket-jumping and slide-canceling remain essential for repositioning during base assaults, while wall-running allows defenders to re-engage from unexpected angles.

Did You Know?

• Onslaught was one of the original modes shipped with Unreal Tournament in 1999, making it older than several entire FPS franchises.
• The credit economy means a team can lose the kill count and still win the match by out-spending the opponent on turrets and repairs.
• Control points provide passive, continuous credit income, so a team that holds more points can sustain a longer siege even while taking casualties.
• The mode's simultaneous demand for offense and defense makes it the primary vehicle for competitive team play across the entire Unreal Tournament series.
