Hidden things not in walkthroughs

So I was watching a vid of original FF, second mission where Minuteman is alone then meet Mentor at the end. After getting Mentor, the player goes to this container by the guardhouse, smashes it and uncovers an experience canister.
When I first bought FF back when it was new, I got one of those guidebooks. I have also read some online walkthroughs since then. None of them ever mention this canister in the second mission.
Just wondering if there are other hidden things like this.

Can't say that I really know of any, to be honest. I didn't even know that there was a walkthrough for these games!

I just remember that there are usually a few hidden cannisters in almost every level. Usually experience or the yellow prestige cannister.  Also i think you get more prestige after a mission if you dont damage the city much. Im not sure though. Its been so lon since ive played the campaigns!

Yeah, plenty of walkthroughs can be found on the web today.

Yes but most of those hidden are usually in an alley, on a rooftop, etc. Sometimes you get an odd one like under a fountain, a burger sign, etc. but those you can see the edges of the canister from some angle.
This one I mentioned from the video, there is no sign it is there, you have to know the right container to whack to get it.

I know of a Prestige one under a truck in the exact same mission, but I don't know if it's missing from the walkthroughs. Let me know if you want specifics.
