I could be wrong, but in my opinion what is attached is not what we now call a mod. This is alpha version 0.4.5 of OpenXcom itself, the predecessor of OpenXcom 1.0. At first glance, apart from vanilla UFO, there is nothing inside, and indeed it is trimmed, since then the game was not fully realized. Launching it now by itself should be easy if you follow the instructions in the archive. It will only be necessary to add the data of the original UFO game (previously used this format) to the DATA folder and run the attached exe-file. As a separate mod, it cannot be used in the archive.
But this is just one more way to play vanilla, and even incomplete. It is much easier in the same OXCE to turn off all the mods and play it.
You both are right. I've just deleted my post. I was a bit excited about this description, as I have no idea how to make a single, coherent mod for everything in it:
Current feature list:
http://openxcommods.weebly.com/download.htmlnew tank type - battle mech! it's a battle mech. need i say more? based on the sectopod chassis, but with 50% more badass. (actual results may vary)
tank shells will now cause small explosions
training facility added - slowly increases soldier's stats, using the same formula as apocalypse
medical bay added - decreases wounded soldier convalescence time
researchable disruptor and gauss cannons for hovertanks and crafts
combat armor added, purchasable from buy interface
power armour replaced with re-coloured TFTD ion armour
flying armour helmet graphics altered
incendiary grenades
stun grenades
flashbangs - explode immediately, no priming, reduces reactions, accuracy and detection radius for 2-3 turns
terror missions at military bases (new map type) with military personnel (new unit type) with flashbangs and all mundane weapon types available
soldiers, if issued with pistols, will grab a melee weapon in their left hand, if one is available
added police, they will show up as local law enforcement on terror missions and actually fight aliens
Again, apologies to Reaver for clogging his thread. Please feel free to delete this post.
