Dock Duck Shoot is a TimeSplitters 1 Challenge. It involves duck hunting along with a rival alien team.

Briefing

Well, this is it, the big Pro Am Duck Shoot. You're up against a pretty tough team from out of town. To get the trophy you must win the match with a score of at least 100 in 7 minutes.

Strategy

The Aliens will often be equipped with the Grenade Launcher, so be careful when they're around. It's best to make them your main target if they are near you. The rest of the time, shoot the ducks.
