Heh, try downloading it an see for yourself.
There's a large change log that comes with it.
But, in short:
-Totally revamps sensors and weapons on most (if not all) objects in the game. They have been altered to be more realistic based on publicly available information
-The AI has gotten a major upgrade and are now more deadly
-The noise levels of boats have been rescaled
-Adds (a lot) more AI units
-a bunch of other stuff that I don't remember
Pros:
-See above
-Almost never has any bugs, and when one is found it is quickly fixed.
-You get active community support both here and on Commanders Academy (
http://www.commanders-academy.com/forum/content.php )
-More stuff gets added or changed periodically.
Cons:
-Doesn't add any new playable platforms. However, LWAMI 3.10 has a new feature that replaces one of the Kilos with the Russian Kilo B-871
Alrosa, a kick-ass variant of the standard Kilo. New model and everything.
-Doesn't fix some of the hard coded bugs and problems in DW.
So give it a shot!
