I have the distinct pleasure of introducing the newest site page here at StrategyCore: Enemy Unknown Alien Stats. That's right, everything you wanted to know and more about what makes Sectoids, Floaters, Etherals and Chryssalids tick. It includes statistic tables for all skill levels as well as a wealth of knowledge unrivaled anywhere. The pièce de résistance is an equation to calculate those values directly. As an added bonus, most of the tables come bundled in a handy spreadsheet which you can download from our files section. So take a look today and satisfy your curiosity!

Thanks everyone! Unfortunately (for me) the fun is not over. There are still minor bits of data which need to be added yet. After that, I'm sure everyone would appreciate my alien stats from TFTD, no? :D

Great work, Zombie!  And I must say that I, for one, will be very happy to get the TFTD version...I started to ask if you were gonna do one yesterday, but then decided to hold off a few days so as not to steal any thunder from what you have done already!

Thanks

I just completed another major research project into alien stats today. In short, I edited each alien stat in the executable and tried to link it to a unitref.dat offset. For the most part, this plan was very successful as out of the 39 stat bytes, four do not show up in unitref. (And two of those are attributes which probably only apply to unitpos). In addition, I figured out another unknown so now we are down to 8! :D

"So, big deal. Who cares", some of you may be saying. True, it probably doesn't affect most players of the game, but for those of us who test religiously, this helps out tremendously when looking at unitref.dat. In fact, if a stat is found in both places, it is easier (and safer) to edit a unitref value than going into the executable as the changes only hold for a mission and not the whole game. I added those unitref offsets in StrategyCore's Alien Stats page in hopes that someone who is researching this can figure out some of these unknowns. Please contact me if you happen to stumble across something! :)

Figuring out which alien stat corresponeded to a unitref offest has had some fortunate side-effects. It allowed me to deduce a complete theoretical executable stat listing for the Zombie! Up until this point there were some major holes left for this creature, so a full listing seemed improbable. In addition, past searches of the executable yielded nothing as the list was incomplete. If anyone is willing to search it with the new string, I would be very grateful:

17, 7, 0, 0, 40, 84, 110, 40, 84, 0, 0, 80, 4, 4, 4, 4, 4, 0, 20, 0, 1, 0, 3, 3, 18, 18, 0, 13, 0, 80, 0, 4, 0, 0, 57, 0, 2, 3

I must mention that MikeTheRed did a comprehensive search for me a while back and came up empty-handed so it is possible that Zombie stats are not found in the executable and are calculated on-the-spot as needed. Either that, or another game file has them hidden somewhere. As always, I added this new info to the alien stats page. :D

Hm. Could Unknown 5 or 6 be the "rank" of the alien, for morale purposes?
2 = grunt, 3 = specialist (engineer/medic/navigator), 4=leader, 5=commander ?

I doubt it. Byte 1 in the alien stats already represents rank. Besides, the Silacoid would be the "commander" as it is the only creature with a value of 5, all 2x2 units would be leaders as they have a vlaue of 4, all the other aliens and units (except Sectoids) would be specialists with a value of 3 and the Sectoids would be the grunts with 2. Unknowns 5&6 fall next to static alien characteristics (height) so one would assume that those unknowns are related to what is next to it somehow. We thought it was width, but Bomb Bloke did some limited tests and preliminary results show no difference in accuracy determinations when shooting at the alien. Any other guesses?  :D

Here's a thought - the zombie (and perhaps even the Chryssalids that hatch from zombies - unless you've verified that they default to the beginner level stats) may have the stats stored independantly of the main stat table. I'm guessing this would be somewhere in the tactical portion of the game.

Ok, is the CE executable (UFO Defense.exe) a combination of Geoscape.exe and Tactical.exe? If so, I ran a quick check through the CE again with shorter zombie string combinations and still came up with nothing. Guess I'll try the DOS Tactical.exe next. I have a sneaking suspicion that it will not be in there either. Any other places I should check before we chalk this up to the game calculating zombie stats? :D

Chryssalids formed from a zombe always have stats equal to the core, and those are found in the main executable.  :)

Ah, sorry... missed the rank field in front of my nose. Guess #2: some sort of stun reduction/resistance, perhaps? Since it is highest for the compact mass of rock, and least for the fragile sectoid?

Yes, the CE executable is a combination of the two. Even with the XComutil split executable, they're still the same - they just start at different locations. The dos version would be by far the best to search for your stats.

Note that the stats may not necessarily be stored in the exact same manner as they were in the master stat table. You'll have to look for variables close to each other that mimic the zombie stats you're after. For all you'd know, the programmers could've manually set the variables one after the other during the turn-this-unit-into-a-zombie subroutine - and out of order.

Damage modifiers for the different damage types are found in the executable in a separate location from alien stats (this includes stun).

I did some minor testing on stun recovery rates for the different units in the game (soldiers, tanks, HWP's, civilians, aliens and terrorists) just for the heck of it, but that number always seems to be 1 pt/turn. Unknown 4 (byte 20) of alien stats is always 1 so I thought that this may be recovery rate. Unfortunately, after editing byte 20 to 10 and alien stun to 10 in unitref and then waiting a turn the rate was still 1 pt. Darn. It may be a unitref stat as there are a couple offsets which are always 1, but I haven't found it yet. :)

NKF: I'm currently searching the DOS version of tactical.exe for the Zombie stats, but let me tell you it's really difficult trying to search with one value and then looking at the numbers which surround it to see if they are in the Zombie stat string. This will take a while.  :D

Is that stun recovery rates for active large aliens, or inactive?

A KO'ed Reaper goes down by 4 stun/turn (which doesn't help it wake up faster, alas)...one for each section in UNITPOS.DAT.  I don't recall testing live ones recently.

That's for active and alive units. The stun recovery rate seems to be 1 pt/turn (even for Reapers). So unconscious Reapers receive 4 pts/turn? Interesting! I'll have to check the other large units (Sectopods and Cyberdiscs) to see what numbers they put out. (They should recover in the same manner as a Reaper since once they are stunned they stay that way). :D
