    A Kingpin Mod - Blood Money 616

    A KINGPIN SERVER MODIFICATION Many Mods incorporated under one server roof. AUTOMATION - hypo_v8 / theghost / mrfredz ANTI-LAG MOD - hypo_v8 / theghost BLOODMONEY - hypo_v8 / theghost / mrfredz This project is just about taking KINGPIN one of the most fun 1st person shooters of all time and making it better than it use to be, maybe even making a few addons that will make the game even more fun for a while or as long as we can. 1999 the time KINGPIN was developed put this 1st person shooter ahead of everything on the shelf. It was the first game to have locational damage quarters. The 1st game to go too far! This is not a G rated game!

    Tanki Online Accelerator

    Tanki Online Accelerator

    Speed up your Tanki Online gameplay by up to tenfold.

    ALERT! There is a problem with the installer, please do not download until the problem is fixed. Sometimes, playing MMO games in the browser can be slow, buggy and may not even work at all. Very simplistic, very minimalistic, this program can speed up your playing by tenfold - because the actual issue is the browser's own elements. As you can see, it doesn't HAVE any elements to slow down gameplay. If you like it, please send me a friend request on Tanki: TheSpyOfDeath
