*When downloading, go to the site, then click Mods, then the Madmod version you want (RA2+, YR+ or YR). This opens a Game Information window- click Download.*
Madmod is available in two forms: the Red Alert 2 original, and the new Yuri's Revenge variation. The RA2 version is older, but a bit more insane (!), featuring units like the HoverCow, Stupidly Powerful Tank, Buzzy (an infantryman with a Grand Cannon) and the Flying Submarine, as well as the Harrier Launcher (in the Image Gallery). The YR version features the Sub-Aquatic Aircraft Carrier and the Mobile Sentry Gun, as well as variations on the old units (like the Spinning Top Tank). There are loads of changes, but not all of them are bug-free; you can re-enable the buggy units using the TibEd version (see downloads page).
Red Alert 2 v1.006 or later; TibEd*
-or- Red Alert 2 v1.006 on its own
For normal version: YR v1.001; basic knowledge of Windows
For TibEd version: YR v1.001; TibEd 1.53* (from Tibed.net)
*TibEd is not usually required; it's just safer to install that way.
Note that TibEd *is* free, it just sticks a delay on the startup screen after a few days using it.
Having just noticed that EA have confirmed development of Command and Conquer 3, I've decided to wait for that to come out before doing a new Madmod. It seems natural that Madmod 3 will be a mod for C&C 3, although the release date is bugging me a bit (it's at least a year off).
Anyway, the old versions are still around, although I don't foresee any great surge in popularity. If anyone fancies helping me out with any future mods (I'm thinking about UT2004, Half-Life 2, Zero Hour and Pacific Assault), I could do with a hand- I have an astounding lack of talent.
