Call of Duty: Infinite Warfare‘s Double XP event recently appears to have highlighted a fundamental problem with the game’s XP balancing, where the double XP yield appears to only be limited to the Score XP, leading to the overall XP multiplier being closer to 1.2x-1.4x than being truly double.
However, whatever the problem is, it appears it wasn’t by design, and it appears to be unintended- Infinity Ward’s Joe Cecot posted on Reddit (verified via his own Twitter), explaining that Challenge XP and Weapon Challenge XP are not currently doubled under the Double XP events, and neither is Match Bonus XP. Cecot said that Infinity Ward would look into fixing all this a bit, and bring it closer to what players expect (which would probably be how Double XP was handled and handed out in Treyarch’s Black Ops 3 last year).
That said, he also pointed out that the team did not want the XP yield rate to be crazy, so maybe players shouldn’t expect the game to get too generous. Call of Duty: Infinite Warfare is available now on PS4, Xbox One, and PC.
