All the stuff they promised
"What is your major malfunction?" is probably something the QA testers on America's Army hear day in, day out, without it ever really becoming funny... Still, they do a good job, and the latest fruits of their labours have finally arrived as part of today's America's Army patch.
Fixing many bugs and introducing a number of new features (a River Basin map, a new scoring system, binoculars, iron sight movement, a new honour system, etc) the patch weighs in at a pretty sizeable 45MB for those running the current version 1.3. Anybody still using v1.2.1 is looking at a 74MB download, and if you fancy trying AA for the first time, you can look forward to hauling a 290MB installation file down your copper.
Anyway, each of the upgrade files and the full game are available from the official home of AA downloads.
