Well, it takes a while to get the AI and gameplay loopholes figured out. In the meantime it is still a pretty good run.
I finally beat Alma as my second city; apparently like someone already said here, this is about the last city most people take. It was pretty damn hard beating the map with level 3 and 4 mercs, but we did, although I lost one of them. The upside to doing this map first is that there were a ton of awesome rifle drops; I think I have about a dozen rifles, and half of them are tricked out with scopes, plus three laser scopes, a law, a FN-FAL, sniper rifles, lots of Spectra armor, etc. etc.
As for getting the commando out of the room he was held up in, I found that blowing down a wall was not necessary; in fact, as soon as the wall was gone the jackass would initiate combat and kill someone immediately most of the time, as if the exploding wall were about the same as opening a garage door.
What I ended up doing was to use a teargas grenade round that I was lucky enough to find. I didn't think it was working earlier, because I didn't wait long enough in RT mode for the teargas to spread and take effect... realtime is slower than I realized. Another tactic is to put a couple mercs outside the door you are going to storm, but out of the enemy's line of sight. Drop a smoke grenade near the door, and then have someone at some distance spring past the door and the enemy's line of sight; hopefully the combo of smoke and the target running means they won't be shot too badly. Once the enemy has blown his APs on that guy, send the others in to burst fire him into hamburger.
The mods sound kind of fun, although that burst fire sounds a bit ridiculously overpowered at some settings, especially if the AI doesn't know how to use it. One thing the game really needs is better grenade tossing, it is almost impossible to get a grenade into a doorway right now, which rather sucks. I think that the HAM mod has some fixes for this, right?
*Edit* still playing the pre-1.13 version. I figure I should see the game as is was originally made, and it is still quite fun despite some annoying quirks.
