Mercenaries, Spies and Private Eyes just hit DrivethruRPG. It uses a variant of the Tunnels & Trolls rules with a beefed up skill system.
About bloody time... tho' I'd love to see it get a revised version in a manner not unlike T&T...
For those who don't know, the skill system moves the AP for skill based saves to the skills themselves. So each skill has a level and an experience point track. Plus the character does as well, which raises attributes (in a much less epic progression than pre-7 T&T). It's pretty good, and works pretty well.
It has the same issue with rather high TN's and low chances as T&T, but a good GM can work that easily.
