Wildfire adds some new weapons, changed maps and terrain like long grass, but
fails to deliver a solid story. For the most part they should have just revamped
the graphics and contents rather than try to add a new story line that you
really don't hear much about after the initial contact. You don't encounter
“drug barons” or anything of the sort. Also, this version is 5.0,
I recommend waiting for version 6.0 as it not only has all the previous
additions but upscales the resolution to 1024×768 (which really helps when you
have a 22inch screen like I do) and replaces about a dozen of the mercs with
much better ones.
Overall, the graphics are totally outdated by todays standards, the sound and
voice acting can be irritating and poorly scripted at times (especially the
newly added character lines) but despite all that, it can be fun and
challenging – not as hard as some people make it out to be and the new
weapons can make up for that.
Note: you may have some issues trying to get it to work on a Vista PC, try
using compatibility mode.
