005 is an arcade game released by Sega for Sega G80 hardware in 1981. The objective is to take a briefcase to a helicopter, while avoiding or stunning enemy agents. 005 stands as one of the earliest examples of a stealth game.
It is a stealth action-adventure game. A spy armed only with a gas canister must avoid enemies as he explores an open-ended overworld with buildings and warehouses, where he must dodge enemy flashlights and use boxes as hiding spots.
