Undisputed: The Championship Upgrade Pack

The Championship Upgrade Pack was developed by Steel City Interactive and released on 28 October 2025 as downloadable content for Undisputed. The pack was published by Deep Silver (PLAION) and was presented as a premium bundle intended to expand the base game’s roster and presentation options as part of ongoing post‑launch support.

At launch the DLC was promoted primarily through the game’s digital storefronts and publisher channels, with a Steam listing describing the bundle composition and price. The pack bundles four previously announced or concurrent fighter packs — the WBC Pack, the Iron & Steel Pack, the Mexican Monster Pack and the Senator Pack — into a single purchase and advertises an expanded roster of around 30 fighters, including high‑profile names and legends added to the game’s roster. The Steam description also lists system requirements and platform support for the base PC release, while promotion leveraged storefront placement, patch notes and publisher social channels to highlight the content and discounted bundle pricing at release.

Content-wise the Championship Upgrade Pack focuses on roster expansion and cosmetic/presentation additions rather than core gameplay changes. By grouping multiple themed packs together it provides new fighters, apparel and presentation assets that broaden matchup possibilities, career and exhibition variety, and the game’s historical or promotional flavour. The inclusion of named fighters and era‑specific apparel aims squarely at fans who prioritise authentic rosters and match presentation, and the bundle model targets players who may have missed individual packs or prefer a single comprehensive purchase.

Community reception at and immediately after launch was generally positive among dedicated players who welcomed the rapid roster growth and the convenience of a bundled purchase. Commentary from the player base noted that the pack’s value depends on how much a player uses expanded rosters and cosmetic items; some players praised the star names and nostalgic appeal while others observed that the DLC does not alter underlying mechanics and is most valuable to those invested in collecting fighters and customising matches.
