Guides on emulating older games

The third installment of the famous 3D shooter Descent. Hop in your Pyro-GX, dive at high speed into the mines and blast hordes of robots without mercy!

Descent³ features the same 360 degrees, three axis action that the players of Descent and Descent II have come to love, but this time the game has far improved 3D graphics, more diversified objectives, more lethal weapons, and 3 different ships you can pilot.

And for the first time in the Descent series, you can actually fly out of the mines and explore outdoor areas.

Descent³ was also designed with multiplayer play in mind, and features a lot of mutiplayer game modes: the classic deathmatch, teamplay, capture the flag, monsterball (a kind of soccer with giant balls) and entropy.


The last update was v1.4, released in 2000. If you got this update, please do upload it to this webpage!

Late to the game Wink Bought old G4 Mini 1.42, removed 2 resistors, now 1.57GHz. I added a 128 SSD and OS9 (Lives!) So revisited Descent, runs like butter at 1024 rez. Have an old 17" KD Trinitron to scale screen down to try some older games that cannot do higher screen rez. Cheers

I've managed to find some patches (both official & unofficial) for Descent 3 Mac here:
Unfortunately, I have yet to find an OS X native one. I don't think Interplay released the source to the D3 engine.

Only PPC applications which are "Carbonized" can run under directly OSX. As this application was originally for OS 8.0 it probably predates the Carbon Library.

Anyone know how to run this in OS X without Classic or Sheep Shaver?

Unfortunately the Mac port has a bug which was never fixed which gives you a choppy framerate no matter what machine you're running on. Yet another example of Mac gamers getting the shaft on ports due to sloppy programming.

Should run smooth as ice with a Voodoo2 on a G3 or late-model 604e. I say should, because it's almost playable on a 603e.

I won a copy of the tie-in novel for this game, Descent: Stealing Thunder, from an on-line contest Interplay did when they were promoting it. I didn't think I would win because after I entered the contest, I found out it was only for US and Canada, but they sent it anyway. It wasn't Pulitzer-Prize material, but it wasn't boring neither. It explains what happened to the material defender after his ship jumps to an unknown location at the end of Descent II.

He finds his way back, Dravis tells him his contract isn't over yet and he, along with a romantic interest and a sidekick, engage in the final campaign, which ends with the defeat of the aliens responsible for the virus. They were described as ape-like with arms that reached the floor and glowing red eyes like some sort of Morlocks (the bad guys from The Time Machine). The novel ends just before Descent 3 begins, with the material defender drifting away to his death, but they included the first chapter of Descent: Equinox to imply he survived.

As for the game, it's good but the hardware demands are too high. While Quake III Arena and Unreal Tournament run fine on my G4, Descent 3 only gives a good frame rate at the lowest detail level. And even though, performance is still choppy on some areas. I still recommend it, though.
