I took Aralez's last input as a suggestion that I should delete all saved games and then should uninstall and reinstall UFO:AM on my WinXP machine. I knew this day was coming.
So, I backed up my 5.6 to 6.61 saved games to CD. You can get the whole CENEGA subdirectory onto a single CD if you remove gamedata.vfs.
I actually saved my January 22, 2004, gamedata.vfs into another folder on the hard drive before deleting the whole CENEGA folder.
Then I uninstalled, deleted the CENEGA and UFO Aftermath folders, rebooted, and reinstalled UFO:AM. I updated to 1.3, ran the game, saved the Default Profile, quit, put 67_mod.vfs into the subdirectory, ran the game, and then created a new Europe Hard profile with RB6.7, and pressed Play. So, now RB6.7 it's setup as fresh as it can be, and I'm fighting off poppers in my first mission with Universal UZI ammo and TNT. We'll see how it goes, when I get time to play some more.
Meanwhile, I did a File Compare (fc /B) between my new April 12, 2004 gamedata.vfs and my older January 22, 2004 gamedata.vfs, and there were No Differences encountered.
So, I take that to mean that my old CDROM and my new DVDROM installed the gamedata.vfs in exactly the same way off the same UFO:AM CD that I purchased last year. Both pieces of hardware produced the same gamedata.vfs file on the same machine, according to file compare.
Hopefully, that means that my gamedata.vfs is NOT corrupted. And, hopefully, I won't get any frozen aliens or SPIT in my inventory during my next missions.
As they say, time will tell.
I'm on my fourth RB6.7 mission with no frozen aliens so far! No spit and no invisible icons in inventory, though there have been three opportunites for SPIT and BOOM to transfer over to inventory, if it was going to do so.
Yay! No frozen aliens.
Lots of poppers and spitters, and I did the city missions so that I could use cover and do ambushes and stay alive. I kept all four soldiers alive until this fourth mission. There's a Cudgel carrying a LurkerGun in my fourth mission! I thought BlackAlmaz didn't know what he was talking about when he mentioned BFG's in the first missions, but I guess BlackAlmaz was right.
While the LurkerGun is killing my team on burst one soldier at a time, I'm running for cover, dodging poppers, and switching to grenades. I'm using the convergence of concrete fences for my trap. Everyone dead now, except for my best person and he's just finished healing with a medical pack. I run back to the corner of the fence, lean around the corner and toss a grenade. Down the Cudgel goes. Get over to Dead Cudgel to see what he was packing, a LurkerGun with no clips in it now.
If you are wanting a serious challenge, it looks like RB6.7 is just what you are looking for. It's was actually kind of fun. I'm going to try to replay the same mission and see if I can win it without losing as many soldiers.
Anyway, uninstalling, deleting saved games, reinstalling UFO:AM, and starting a new game profile appears to be the way to go with RB6.7, so far anyway. I'm about ready to try ALLITEMs, or maybe not.
