The Secret Service is a stealth action game, in which players can become Eggsy, go on an extensive campaign, and infiltrate a multitude of enemy bases, all while trying to protect their headquarters.

It is the story of Eggsy, a spy who has been sent to various locations to steal information while trying to protect his base from attack.

The gameplay is similar to King of Thieves. You have to steal various items from other bases, and you must protect your base from enemy attacks.

It is also similar to Gunpoint, in that you have to build a base, and hire guards.
