Here's an updated FAQ and Rules for the Commanders 2.5 expansion for Risk 2210. The cards themselves are still too large to be hosted here (26 MB), so they can be downloaded via this link:
http://208.100.1.80/commanders_2.5.rarIncluded in this expansion are:
• An upgraded official (Avalon Hill) Tech Commander expansion (new backs and graphics, 20 cards)
• An upgraded official six Major cards expansion (new graphics, 6 cards)
• The official 6 factions plus 3 additional factions from Geoff (new backs and icons, some rules clarifications, 9 cards)
• An upgraded Commanders 2.0 expansion. Added new graphics, rules tweaks and spelling fixes for existing cards plus many totally new cards (87 cards).
• Advanced Tech cards with backs, some with new graphics and rules clarifications (39 cards)
• A revamped Global Warming card for Geoff’s Antarctica map expansion (I figured a Naval commander would be the first to know and report about rising ocean levels, 1 card)
• An upgraded Risk 2210 player aid (reflects the new 2.0 commander abilities)
• Energy cost templates and game markers
All in all this will give you 160+ additional cards to play with. Print and cut them out, sleeve them (you can find correct size sleeves online and on eBay) and you're good to go.
