The fifth Free Bundle has just come out today, including a few games with definite retro interest. There is Super Smash Land, a Super Smash Brothers clone for the PC designed to look like the classic greenscale Game Boy, plus a platformer called Alter Ego that has been simultaneously released on PC, ZX Spectrum and NES.

It also features a commercial PC version of Slaves of Rema, a gamebook styled game much like the Fighting Fantasy series, plus a few other titles. And it's all free to download, no registration required. Finally, if you haven't seen these before, the previous four bundles are still available, also free downloads.
