The first trailer for the final season of “Teen Wolf” reveals four big surprises: Tyler Hoechlin, Colton Haynes, Dylan O’Brien and Charlie Carver.

The preview (above) released Monday hints at the war in Beacon Hills that brings Scott (Tyler Posey) and his crew to fight yet another enemy rising in the shadows, which will play around with the group’s fate.

Haynes and Carver, who were last seen in Season 2 and 3 are both seen walking through the halls of Beacon Hills High.

“You didn’t think you were doing this without me, did you?” Stiles (O’Brien) asks his old friend to begin a series of twists and turns for the final season.

“Without us?” Derek (Hoechlin) then chimes in to reveal another character return. Hoechlin was last seen in the series back in Season 4.

Season 6 of “Teen Wolf” premieres July 30 at 8 p.m. on MTV.
