CJ initially obtains the jetpack for The Truth in the Black Project mission which takes place in Area 69. The Truth takes the jetpack after CJ has escaped Area 69 and flies in the jetpack to meet Truth. After the Green Goo mission, where The Truth asks CJ to obtain another secret from a government train, (the substance of the Green Goo is never explained in the game), Truth gives CJ the jetpack, which he will need to steal the Green Goo. After this mission, CJ gets to keep the jetpack which respawns near the Flying School office in Verdant Meadows.
Roman engineering did not have any secret weapons. None of the Roman engineering achievements were kept secret.
Don't be ashamed that you had to ask, because the secret achievement is impossible to just guess what it is. I came across it on accident when trying to get the bullseye achievement. All you need to do, is collect exactly 69 coins in one game. Do so, and the achivement's yours.
If you Prestiege, that's one secret achievement.
In GTA: San Andreas, Area 69 in Bone County really becomes accessible with the mission, Black Project. In this mission, The Truth persuades CJ to sneak into the Area 69 inner laboratories and retrieve the secret that is hidden within this secret government location. Once CJ has obtained the item (which turns out to be the prototype of a jetpack) he is able to fly up out of the compound, go and meet The Truth and give him the jetpack. Later on, The Truth asks CJ to obtain another secret from a government train, this is the Green Goo (what it really is - is never explained in the game). After this mission, CJ gets to keep the jetpack which respawns near the Flying School office in Verdant Meadows.
