Now this is some classic gaming. Cannon Fodder is a game I remember playing on the Amiga and it's being kept alive with a cross-platform open source game engine called Open Fodder.
After playing with it myself with the original Cannon Fodder, it really does seem to work nicely. Plenty of memories came flowing back with this! Shooting anything that moves, throwing grenades, blowing up buildings, driving tanks and more it still holds up quite well.
You do need a copy of the data files to play Cannon Fodder 1 and/or 2, which you can grab them easily enough from GOG:
