Due to a programming oversight, in the first level, "Courier", of the Nintendo 64 version, it's possible to successfully complete the level quickly, without completing all the objectives and failing the mission. Before collecting your equipment from the safety deposit box, either turn the alarm on or harm a guard or civilian without killing them. Then collect your equipment from the box and exit out of the building.

In the Nintendo 64 version, the yellow dumpster found at the beginning of Turncoat was inexplicably removed from the European version.
