Can someone who actually has the time and inclination to watch two thirty-minute videos give a reasonably objective breakdown of this? Are there any gameplay improvements (as opposed to just content additions)? It seems like the guy just babbles and occasionally makes content references instead of actually talking about the game. Just watching the first five minutes, it looks like the "burst-fire sniping" problem of the AI might have been resolved, but that's not much of a sample size.
There is nothing new or improved gameplay wise.
It's basically a set of new maps, with a new story and NPC's, some new MERCS and new items.
Furthermore, there are less maps than JA: BIA, however the maps are much bigger. Moreover, the maps have some more variety than in Vanilla.
Jagged Alliance: Crossfire is like the prior released DLC's, but then a much bigger version of it.
