Project Hotseat is a 2-player game project by Jan Willem Nijman, with the focus on weapons. The latest demo contains 68 of them; Examples are rocket machineguns, laser cannons, invisible mines, toxic sprayers, and ducks of doom. There are 6 maps to try.
The game is made for the gameplay, so the graphics aren’t very special, and instead of a fancy menu there are shortcuts for most of the “debug” options.
Two weapons can be carried at a time, and ammo is depleted within seconds. Whenever you are weaponless you can still jump on your enemy’s head to deal some damage.
