WWE 2K19 will introduce a new Towers mode, in which you'll be pitted against a string of opponents in a row. The mode will boast rosters filled with superstars, along with varying win conditions and limitations to challenge you to think outside the box (or ring).

The official site details the new mode. Towers will come in two varieties: Gauntlet, which must be finished in one session without a loss, and Steps, which let you play at your own pace. Opponents will range from current wrestlers to WWE Legends. The goal for a Tower will vary between conditions like beating a score or simply making it to the end, with buffs to you or your opponent peppered in for variety. The match types can range from Steel Cage and Submission to Iron Man.
