I will try to find the CD with the various versions of Ack on it, upload the files for Ack-3D and AckNex and provide you with the links. It is allowable to distribute these files. It may take me a while to do it (have to find the CDs, etc), so give me a few days, if you don't mind.

That'd be much appreciated, I would very much like to know what they were like to use

I got acknex 3 from the conitec site as it is a free download but ack 1 and acknex links were broken when I tried to grab them

You will need a DOS system (Win95 should work) or a DOS emulator to run Ack-3D or AckNex.

Ahh no probs, I have a dos and 98 pc next to my xp and vista machines for old games

i'd just use dosbox

My CDs are scattered here and there at the moment, but there are a few places to download Ack on the web. The one link I provided above has a download section at the bottom of the page:

Here are a few more links that I found via a Google search:

This one is from the Wiki entry on GameStudio:

Here is a link to the GameStudio page as it looked back in 1998 (via the Internet Archive):

And I like visiting the forum from that time because you can see me there :

You would think me having been with GameStudio all this time that I would have learned something, but noooooo ....

I can see who's a real DOOM fan here... DAN .. lol

While reading this I will caonfirm with my opinion that interactivity has pretty much been removed from the gaming experience.

And like mentioned, I was always clicking the 'use' button too on so much stuff only to be disappointed. I WANT to be surprised when i click on some computer gadget and some video comes on, or something goes haywire...

Now, I realize that it's a lot of work to make so many things have interaction... But it would sooooo be worth the effort for the player!

Playing Return To Castle Wolfenstein I imagined so many things could happen messing with objects or activating things.
Fortunately in that game, they did have 'some' interaction and it was cool.

If anyones looking for something 'unique' to make an FPS game more attractive, I think this interaction is a good start (or any game for that matter)
