''Secret Agent'' is a 1992 side-scrolling PlatformGame released by Apogee Software (now 3D Realms) and based on the engine of the earlier ''VideoGame/CrystalCaves''. Much like its predecessor, it was released as three games and licensed as {{shareware}}: the first game is free as a teaser, while the other two were made available for purchase (and can be still bought from 3D Realms or from [[http://www.gog.com/gamecard/secret_agent GOG.com]]).

The games feature a [[ExactlyWhatItSaysOnTheTin secret agent]], who, throughout the series, infiltrates the islands occupied by the evil organization [[FunWithAcronyms DVS]]. Each island is covered with DVS bases where our intrepid agent faces villainous guards and reckless robots alike, along with an assortment of traps, while trying to find and destroy the radar on the level and then blow up the elevator door to escape. On the final level, the agent seeks out blueprints; collecting them and exiting the base ends the game and treats you to a nice picture as your reward.

If you're looking for the 1960s TV series, try ''Series/DangerMan''.

!!This game provides examples of:

* CollisionDamage
* DeathThrows
* FloatingPlatforms
* GogglesDoSomethingUnusual: They cause a bunch of previously "invisible" (=nonexistent) platforms to appear.
* InstantAwesomeJustAddNinja: The Ninja and Ninja Master {{mooks}}.
* InstantGravestone: Happens to the human enemies once you kill them completely. The higher-ranking enemies turn into lower-ranking enemies until you kill the lowest, weakest form, at which point they become a gravestone (which can be picked up or just destroyed for points.)
* InterchangeableAntimatterKeys: And picking up a key when you already have one of the same color will make it disappear, (probably) making the level {{unwinnable}}.
* InterfaceScrew: The question mark, which reverses your left/right controls.
* InvincibleMinorMinion: The robot that floats one square above ground.
* InvisibleBlock: See GogglesDoSomethingUnusual, above.
* JumpPhysics
* NoDamageRun: You get a reward after finishing a level if you pull it off.
* OneBulletAtATime: A power-up allows you to fire a total of two bullets at once.
* PainfullySlowProjectile: Enemy bullets travel the same speed as you can run. Your own bullets are a bit faster.
* RobotDog: One of the enemies.
* ShoutOut: Each of the three episode names: [[Film/TheHuntForRedOctober "The Hunt For Red Rock Rover"]], [[Series/GilligansIsland "Kill Again Island"]], [[Film/DrNo "Dr. No Body"]].
* SuperDrowningSkills: Touching water means instant death. (Except at the end of the second episode, where you leave the island in scuba gear.)
* SpellingBonus: Collecting the letters S-P-Y in order gives a score bonus.
* SprintShoes: Literal shoes that make you run fast (and, more importantly, jump further).
* ThiefBag: One of the things you can collect to [[ScoringPoints earn points]].
* ThreateningShark: Some of the pools of water have sharks in them. They do one hit point of damage, which makes no difference because you'll land in the water a split second later and die.
