In this game you have to help a cute little green animal switch off some kind of "evil" mechanism.
The "power off switch" is hidden somewhere in high towers. On your way to the target you need to avoid
a lot of strange robots that guard the tower.
That sounds all like a normal jump and run game. What makes this game different is that you walk arond
the tower which is revolving on the screen, so that you only see the 180° that are currently visible.
The game is a reimplementation of the old game known as Tower Toppler or Nebulus.
It was available for PC, Atari, C64. The author was J.M.Phillips and was published by Hewson software.
I have seen the PC version on quite a few abandonware sites. But it is only a DOS version and
uses ugly graphics.
Here are a few shots of some of the available original versions
Because I really enjoyed this game when it was published I reprogrammed it some years ago using PASCAL.
I painted all the necessary graphics on my own (or used POVRAY) and finally got a program that behaves
nearly identical if compared with the original.
Some time ago I decided to port this version to LINUX and C using SDL for the graphic and sound
output. And here is the result.
State of the Work
The game fully playable. Everything is in place. Some more sounds could be added, surely some bugs
are left but there should be nothing too serious.
There is a leveleditor that allows everyone to create new towers and missionfiles. So I am awaiting all your
My rating on happypenguin (please rate me there, excpecially, if you like the game):
Version 1.1.6 of toppler released.
A lot of things happened since my last release in 2007. I had handed
the project over to another developer. But he neither found enough time
to do proper development. He did 2 releases which introduced some bugs
that he was unable to fix.
So I've taken over the project again. Went beck to 1.1.3, fixed all
the problems that were found and this is this release. The following
things have been changed in relation fo release 1.1.3
- fix memory leaks
- proper program ending instead of an uncaught exception
- fix all warnings when compiling
- make compilable on modern systems
- included missions are now in the datafile insted of separate files
- fix joystick support
Thanks to Bill Allombert, who had been a driving force within the last
years making me finally take over again. He also helped with the
production of this release.
We also deprecated the olc CVS repository and switched to darcs. See
below at the download links for how to access it.
Version 1.1.3 of toppler is now available. The changes include
Thanks to the translators and Davd for his mission. Also thanks to Volker for making
crosscompilation possible by providing a simple environment
and by fixing all kinds of things in my build environment that were missing for
crosscompilation. I can now generate the Windows binaries and installer completely on
Linux without any hassle.
- A new mission David1
- New translations: Czech, Rumanian, Basque
- Include the background music within the distribution
Oops, the last release has 2 problems:
The program was not compilable without SDL-Mixer installed
There was a problem in the makefiles that made it stop with an error when trying to install
Both problems are hotfixed in a file called toppler-1.1.2a. This is still the same release
it just fixes the 2 problems. Only people downloading the source are affected.
