Arrow: Legends Of Yesterday Extended Trailer Released

A new trailer for tonight's concluding chapter of the Arrow/Flash Heroes Join Forces crossover event has been released online.

In the trailer, Vandal Savage threatens the lives of Oliver, Barry, and their loved ones. Will the super-duo be able to team with their new Hawk-friends to take down the immortal villain?

Oliver and Barry Allen take Kendra Saunders and Carter Hall to a remote location to keep them hidden from Vandal Savage while they figure out how to defeat him. Malcolm arranges a meeting between Vandal, Green Arrow and The Flash that doesn't go as planned. Meanwhile, Felicity, Thea, Diggle and Laurel work with Team Flash to come up with a weapon powerful enough to destroy Vandal Savage.

The Arrow/Flash crossover conclusion begins tonight at 8 PM ET on the CW.
