File:WM 28 Undertaker v Triple H.jpg At WrestleMania XXVIII, two of the most decorated figures in WWE history, The Undertaker and Triple H, will engage in battle once more – this time, inside the diabolical Hell in a Cell. According to Triple H, when he and The Phenom exit the Cell on April 1, it will mark the end of an era. Hinging on this match are not only the professional legacies of two true icons, but also the future of WWE as a whole, Triple H claims.
