ok...here's the deal...i need to know a game that my friend played long ago...there was this robot...it fought for...dna...there was an elevator...and you went to different floors to find the dna but someone tried to kill you...it was another robot...and there was a dark level you needed a flashlight for...it was 3d? no it was...umm...what was it? please help...the word oasis come to mind...sorry this doesn't make sence..please help any way...for real it was 3d

Destroy all humans? No... What platform/computer was it on?

A Mac, he said so... he even said "old mac".

Ohhhh. Have you asked your friend (if you still are in contact)? How long ago?

iron helix? i know you played a remote probe in that game, and there was some security robot that would blow you up if it caught you. further, it had an elevator and was pseudo-3d (like myst- you went from place to place by clicking arrow buttons, which moved you to the next fixed point in that direction)

[edit]the back of the box describes it as "the most stunning 3-d action adventure game ever created," and says that your mission is to stop a ship carrying a doomsday virus. further, you apparently needed to collect dna from the ship's high-ranking officers in order to gain access to certain areas and computers.[/edit]

Yep, I'm pretty sure he's talking about Iron Helix.

Here's another one... anyone remember Gold Digger? Know where I can get it?

Yes. Some quick Googling produced the demo; I don't know if there's a freeware/abandonware version out there anywhere.

Spacestation Pheta was fun, too.

edit: Actually, they seem to still be around, to some extent, at http://www.tandtsoftware.com/. They'd probably be happy to take your money, even.

The odd side scroller? Yup, I remember that.
