ACES Semifinals is a job in Sly 3: Honor Among Thieves. Its earlier name throughout development, and even in some demos, was Fly the Biplane. The job underwent a few revisions throughout development, which is evident through intermediate builds.
E3 2005 demo
In the April 18 2005 build (the E3 2005 demo), the job is called "Fly the Biplane".
- Story details are omitted from the job's description.
- The objective is to destroy 30 planes, instead of 25.
- There is no way to flip the biplane; in the final retail build, a flip is done with (forward or backward) + . Performing this in the E3 2005 build will cause Sly to do a barrel roll instead.
