All of the early games are available for FREE! at
Abandonia.com - Crescent Hawks 1 and 2, as well as the original Mechwarrior. These will require the program DosBox, which can also be found at Abandonia -

If you register on their forums, you get access to the ISO Cellar. Here you can find Mechwarrior 2 Mercenaries and it's variants.
The Mechwarrior 2 Mercenaries I've uploaded includes the DOS install, which is the only one that works in XP. If you attempt to install this game, please follow these instructions:
1. Download the .IMG and burn it to a cd as an image, not a data disc.
2. Using DosBox(refer to help pages on Abandonia) to mount the cd, run the DOS installation from the DosBox command prompt. Do not install the windows version, unless you love getting frustrated. Use the biggest installation size. Unfortunately, you have to install the game in C:\MERCS.
3. Set the compatability for MERCS.EXE to win95. With the cd in the drive, run mercs.exe straight from windows. You do NOT need to run the game in DosBox, but you DO need to install it with DosBox.
4. Do a little dance, you're one of the elite now.
If anyone wants more specific installation info, feel free to send me a private message - but check the solutions in the Abandonia Forums first.
