This game works with: SheepShaver,

Deimos Rising is a computer game by Ambrosia Software, similar to many top-scrolling arcade shooters. The sequel to Mars Rising, it is available on Apple Macintosh and Windows platforms. It is similar to the scrolling arcade shooter Xevious. The player commands a fighter-bomber airplane known as a VacFighter through twelve progressively more difficult levels. Some of the levels are named after ancient locations or battles, such as Thermopylae or Carthage.

The game builds on its predecessor by using greater color depth (16 bit color, rather than 8 bit as in Mars Rising), alpha transparency, motion blur, improved artwork and a wider range of enemies and weapons.

This game was bundled unlocked on certain Mac OS install disks around 2002-2003. It is included on the G4 eMac Software Install & Restore disk's DVD. No user personalisation required.

Located inside a hidden folder named ".images", is the "DeimosRising.dmg" file, containing the game.

Easiest method of getting to this is via the Terminal and "cd" into the mounted DVD image,
then typing:   open .images  [Enter]

You'll then have access to the contents of the ".images" folder. Double-click the DeimosRising.dmg to mount it and drag the game's folder into your Applications folder or wherever you choose. Should be good to go then.

Note: I don't know if that version of Deimos Rising is locked into this particular model G4. It runs well on Mac OS 9.2.2 and OS X 10.2 to 10.5 on my G4 eMac. - I think I also had it installed and playing well on a beige G3 too, so maybe it'll be fine on any suitable Mac.

The DVD also includes the game "Otto Matic".

[Edit] 2019/12/16: The unlocked version has now been added to this page for easier access.

Latest version of Deimos knows that particular 'Carlos' serial was circulated. Deimos has a codeworm to pretend to accept that serial on that date, lets you play half of one level then crashes your computer.

What really exposes this as a codeworm is the format of the crash notification pop-up msg. It mimics the system trap of the classic OS but looks identical in OSX where OSX should be a different style of pop-up.

I have some codez for some other Ambrosia games: (Mars Rising and Swoop).

Ambrosia seems to be gone for good. Sad

I don't know if it works, but for registration try setting the system date to 20 January, 2002 and then using ...

@hurler What issues are you having? Serial numbers? If so, I, myself, don't remember if I was ever able to register this game...

I like Deimos Rising, but it is so, so, so much inferior than Mars Rising IMO that whenever I touched it, I'd always just go back to playing Mars Rising again. The entire presentation, and the soundtrack, in particular.

Not only is their website completely gone now, but even up to a year ago when their website was still up, it was impossible to actually purchase their games (for me anyway). I had tried to purchase Deimos Rising (as well as escape velocity: Nova) multiple times, over the span of a few months and was unable to. Sad
You could put games into your cart, but you could not finish the checkout payment process.
It would always time out.
I tried contacting their support, once again, multiple times, no response.
I tried contacting their office, left multiple voice mails on their machine, nothing.
If someone would be willing to assist me with getting this abandonware working, I would greatly appreciate it.

For what it's worth, it appears to be down now.

Hello Mikec. I'm afraid the Ambrosia site is still very much alive and still selling those old games.

We have tested their license reactivation/renewing system as still working (as of: 2019/03/29).

While those games are still available for sale or activation from their site, we won't be hosting their full games or making available, serials for them. Thanks for your interest.

[Edit] 2019/12/16: Ambrosia Software is now considered defunct.

Hi, I used to play Deimos Rising when I was a kid and I would love to play it again. However I don't have the serial number anymore. Ambrosia website is down and I couldn't find anywhere else where I could buy a license. Is there any way to obtain a licence or a full version of the game today?

@MikeTomTom - The links are dead: Ambrosia's closed, and their website is gone. [edit] Ah, looks like it's a browser-dependent thing. It certainly hasn't been updated in a very long time, and their automated key-retrieval system doesn't seem to be working, either.

As far as I'm aware, we still cannot host the full games or serials for Deimos Rising and Mars Rising yet.

This and Mars Rising (hey, any chance on getting that up here?) were REALLY good. It's such a shame Ambrosia's gone now.

With this modification I added (dL #1) the unregistered and registered game can see demo play for eleven of its twelve total levels.

Sorry - my bad. I didnt check the publisher's site. I've taken down the download link.

Not abandonware at all. Be careful about posting titles like this because the publisher will come down on the site if people are posting still-for-sale material. In fact, the owner of Ambrosia Software has seen this site because I specifically linked him to it to show him an old project he was credited on.

By the way - if the disk image posted is simply the same file as provided on the publisher's website, then I suppose that is not a problem. Smile

I don't think download is OK, but buylink (which I added) should be OK:

You can still buy the game.
About Mac OS / Mac OS X compatibility. The developer tells: Mac OS 8.6 or newer, including Mac OS X.
