On the
Games page is a number of old flash based games. You can still play some of them using the local debug flash player for your system (linked on the games page).
Furthermore, I've added a game I threw together called
Chain Reaction. This is an HTML5 game, so it doesn't require Flash. It'll just play in any browser.
It's using the same framework I started playing around with for a new version of
Zombie Slaughter. Today I've revisited that and have added a couple gunmen who target the zombies. You can see the green crosshairs on the nearest enemy. It's not playable yet, but a couple steps closer to it.
