Mayhem in Monsterland is definitely one of the technically more accomplished C64 games ever produced, the last truly big commercial release for the machine and one of the best and most beautiful platform games you can get your hands on. Also, it's relatively easy to find a copy of it on eBay. What's more, indie retro developer and publisher Psytronik, have rereleased the game and you can grab it at its shiniest right here. Tape, disk and deluxe versions are available, whereas the game has been slightly updated/patched too. Brilliant!
