"Free as in Freedom, Free as in Priceless"

Welcome to the home page of Piga Software: we are a cooperative of programmers developing free software for GNU/Linux and occasionally other systems, with a particular emphasis on game development. Our software is released under the GNU General Public License version 3, though some individual files within projects might be under other copyleft licenses and are listed in project copyright disclaimers. Some content from our games by MWM may also be available under the GFDL and CC BY-SA on their wiki database.

Although we have used Visual Basic 6, QBasic, Game Maker and even ZZT-oop, most current projects are built in Gambas - a free software BASIC-style OOP programming language consisting of an integrated development environment and run-time inspired by Visual Basic and Java that is well suited to rapid application development. Our particular areas of interest are strategy, adventure and platformers, first-person games and interactive narrative, often with a sense of humour; though we work on whatever suits us at the time, and some projects are developed for a specific use case, as well as general use applications.

More details on who we are and what we do can be found at PigaLore, the Piga Software Wiki; we are also active on the Gambas ONE and FreeGameDev Forums.

  1. Piga Animator is a project to create a suite of 2D animation tools based on machinimatic techniques using digital puppetry and the implementation of procedural elements.
    • Sprite Stage handles sprite-based layered cell animation.
    • Cutout Colisseum is for segmented cutout animation.
    • Speech Generator allows the production of speech files for automated lip flaps, subtitling and text-to-speech.
    • Character Creator will allow for the defining of digital puppets with model sheets and defined traits.


  1. Gambas Performance System is a free software system to create virtual agents and actors for games and animation projects; this can include semi-autonomous digital puppets or fully independent game entities controlled by artificial intelligence.
  2. Gambas Tile System is a free software tiling system for two dimensional games that allows for the creation of scalable, adaptive and low over-head tile worlds.
  3. Gambas Physics System is a free software light-weight physics system for basic simulations of collisions, motions and forces.
  4. Crustacean of Bethany is a prospective project to create a partial Gambas (BASIC) to Lazarus (Free Pascal) and vice versa converter tool for simple graphical user interface (GUI) programs.


  1. Gambas Platform Engine is a free software platform game engine written in Gambas. It was first used in Windys, and a new version with an expanded array of features is under current development.
  2. PS Tech is a project to write a first-person 3D engine in Gambas with OpenGL 2.1 (early alpha).
  3. Gambas Projection Engine is a 2.5D game engine project that provides grid-based simulated three dimensional spaces ala Dungeon Master, as well as more experimental pseudo-3D effects such as graphical scaling.
  4. Gambas Genie (PigaLore) is a project to create a free software real-time strategy game engine primarily inspired by Ensemble Studios' Genie Engine, but also taking in ideas from other engines and games. It was previously showcased in the form of the Lamp Refugee technical demo (Source Release 2).
