The GDS society are hosting an Arcade Jam from Monday December 1st to Friday December 5th! The objective is to make a game for the arcade machines in Flaxman.
There is no theme, but we'd really like to see traditional arcade features, such as an attract mode, highscore table, and short play sessions!
The arcade machines run Windows 11, and can run any executable built for windows like normal, so you can develop a game the same way as any other jam!
There are two arcade machines you can develop for; the standard 2-player machine, and the lightgun machine.
The standard 2-player arcade machine has two sets of player inputs, each containing a joystick, start and coin button, and 6 miscellaneous buttons. Button inputs map to key presses according to the chart below:

The current Sinden lightgun machine is identical to the standard 2-player machine, with the addition of a Sinden lightgun as a third player. The lightgun moves the mouse pointer. Firing triggers the left mouse button input, and the under barrel pump triggers the right mouse button input. Only one lightgun is connected.
If you want to develop a Sinden lightgun game with Unreal, a downloadable framework is available to be downloaded and used on the GDS Discord.
More details about the arcade machines can be found in the downloadable slides on the GDS Discord.
All submissions will be considered for a place on the arcade machines!
