- "Blake Dexter. He will destroy the building and sacrifice his own men in a heartbeat before giving up Victoria. The only thing keeping him from leaving is Layla. I have to take him down before he realizes she will not be coming back. This man is utterly ruthless. He will stop at nothing to get what he wants. I guess we have that in common."
- ―Mission description.[src]
Countdown is the 19th and penultimate mission in Hitman: Absolution. It consists of a single segment, Blackwater Roof. It's the only mission in Absolution in which the entire mission is timed. Also, this is one of the shortest missions in the game.
In the previous mission, 47 kills Layla Stockton, and overhears Dexter, who is on the helipad with an evil plan. 47 rushes to the helipad, where Dexter has planted several dozen mines, which he will detonate if Layla does not come within 5 minutes. 47 evades his guards and mines, and makes his way to Dexter. Dexter is the most powerful enemy in the game, as he takes 4-5 chest shots to be killed, so head-shots or point-shooting is recommended.
After defeating Dexter, he begs for his deceased son's forgiveness, and wants to hold his money. Victoria, disgusted at Dexter's fixation on money, angrily throws the case of money onto his dying body. 47 and Victoria then leave Blackwater Park.
