25 Years of Chase Ace

Chase Ace is a series of retro top-down space shooter games made by some guys from Denmark. This page is an attempt of gathering the pieces, and documenting the history of the games .

1998: Chase Ace

Chase Ace – the first game in the series – was two-player split-screen only and included a level editor. 

It was released as shareware under the label SureSoft, in 1998. The SureSoft label was soon after dropped, the company name was changed to Space Time Foam.

The game was included on a few shareware & game magazine cover CDs.

Chase Ace was developed as a spare time project, just for fun, and to keep three friends entertained...

1999: Chase Ace 2

Chase Ace 2 was developed and self-published by Space Time Foam. It was released on CD-ROM in 1999, and only sold on mail-order via

The game was a direct evolution of Chase Ace, now featuring a "keep 'em coming" single-player mode, single-player mission packs and IPX multi-player modes as well.

Later a patch, some additional fighters, levels and a mission pack was released, free of charge, via the web site.

2007 - 2010:
New Prototypes

Space Time Foam worked on realising the old dream of an updated 3d version of Chase Ace.


The game, first dubbed Chase Ace - Off-World Leagues, later just Chase Ace, reached a publisher demo stage, and was eventually dropped, after years of pitching, meetings and negotiations.

The trailer shown here plus some concept art, were the only publicly shared outcomes of the project.

A number of people worked on and off on the publisher demo over the years. Here is a non-exhaustive list, drawn from memory:

Tobias Thorsen, Peter Holm, Mads Ahm, Rasmus Færch, Carsten Brandt, Rasmus Hartvig Boye, Brian Meidell, Sebastian Aparicio Mogensen, Emil Landgreen and most likely more lovely people...

Also, hat tip for Maarten De Koning and DDM for meetings.

The demo was supported by DFI / New Danish Screen in the first round of support grants ever.
