Building the Hostile Takeover Data File

The Hostile Takeover iOS executable incorporates a data file, htdata832.pdb, which includes all the art, audio, and levels for the game. A prebuilt version of this data file is already in the source tree so you don't need to build it unless you are modifying assets it contains.

Originally all of Hostile Takeover was developed on Windows using Windows tools like Visual Studio and C#. To build the data file on the Mac, the cross platform Mono framework is used.

  1. Install the Mono runtime environment.
  • cd data
  • make IPHONE=1 MULTIPLAYER=1 clean all
    • some harmless warnings will be displayed
  • Mark the data file with a version number.
    • cd ../game
    • ../bin/markversion.exe 1 htdata832.pdb "+++VERSION+++" 1.6

Building and running the Hostile Takeover Multiplayer Server

Hostile Takeover supports single player and multiplayer play. Multiplayer is supported by two server components: a TCP based game server located in the server directory, and an HTTP based server located in the stats directory used for accounts, leaderboard, game history and game stats.

  1. The game server is a command line server which builds can be built and run on OSX or Linux. The game server is does not (currently) build and run on Windows. The production server environment is expected to be Linux based.
  • cd server
  • make REL=1 clean all (for a release build)
  • make clean all (for a debug build)

Please refer to the README.txt in the server directory for more detailed information on how to run the server environment in development and production.


The bin directory contains many command line tools used to build the htdata file. There are also GUI tools for editing maps (M) and animations (AniMax).

The GUI tools have primarily been used on Windows and are best described as 'flaky' on the Mac. If you want to give level editing a try on a Mac:

  1. mono bin/m.exe

See Building the Hostile Takeover Data File for instructions on how to rebuild the data file after making changes to any level, image, sound files or other game assets.
