In this single-player mode the player is able to choose between Black Spy or White Spy to complete a variety of missions filled with puzzles and a cast of enemies, including the enemy spy, all of which are AI-controlled. The story has been developed to be like an extended episode of the 1960s cartoon with a modern twist. The choice of spy does not matter - the player will still receive the same weapons and gadgets on either campaign. Likewise also, there are the same missions each way.
These modes can be played in Single player or Multiplayer. The aim of these modes is to collect 4 artifacts from safes around the map (and a Briefcase in Classic mode to carry all of the items) before the other spy, and then escaping in either the elevator or (in Modern mode) some unusual getaway vehicle. The winner is the player who collects all 4 artifacts from the map and then escapes. This rule applies in both Modern and Classic modes - the only difference is that the 8 Modern maps are all unique and different, but the Classic maps are more like the 1960s cartoon and the original game. The 8 Modern modes are: The Mansion, The Kooky Carnival, The Robot Factory, The Oil Rig, The Haunted House, The Volcano Lair, Area 51 & The Space Station, whereas the Classic mode increases in room size by 1 every level.
In this mode, two new coloured spies are introduced, Red and Blue. These spies are AI-controlled with 2 players or can be chosen in 3 or 4-player mode. These are basically Deathmatch/Capture the Flag style games - kill all other spies and capture their flags to win, and can be played in either Modern or Classic modes.
