I have some remarks again.
§ I have already mentioned the data bug in TFTD that there are places between South Atlantic and Antarctic taken for North Atlantic. I observed lately that alien subs in missions at the North Sea usually have a waypoint in the buggy area causing them to shuttle south and north on the globe. (Sometimes alien subs even take a seat there.) This causes two significant problems: (1) greater alien activity scores at irrelevant areas as Antarctic, South Atlantic, and Africa; (2) loss of sight of alien subs. In the beginning with Standard Sonar you have a hard time to detect alien subs, and this error makes you have to detect alien subs twice.
I found one more buggy place between the Indian Ocean and South China Sea, also taken for North Atlantic. I have not yet observed issues in alien sub movement regarding this place. The only drawback of this is that the settling of a base costs more than it should as North Atlantic is one of the most costly areas. I wonder how floating base attack missions may handle an X-COM base in the buggy places. Does somebody care to confirm this data bug on the PC versions at last?
§ I read on a wikipage "Most experienced Able Seaman is promoted to Ensign if opening present." I discovered that this is not exactly the case. I got promoted a man (7th) with 25 summary improvement points versus a man (9th) with 29. The invisible melee accuracy can't be the reason because none of them has used Thermal Tazer. Can you tell a parameter that isn't counted for promotions? Are some parameters counted twofold?
Here are the "competitors" for the rank:
7 8 9 10 ordinal number
E A A A rank
4 5 2 2 missions
2 2 2 2 kills
2 3 2 5 TU improvement
9 4 7 7 Stamina i.
7 4 8 4 Health i.
0 0 0 0 Bravery i.
0 0 1 0 Reactions i.
3 2 1 2 Firing Acc. i.
3 3 1 0 Throwing Acc. i.
1 9 9 6 Strength i.
25 25 29 24 Total i.
I noticed that aquanauts (and soldiers) gain experience peculiarly according to their ordinary number. For example my 1st aquanaut in my current game just won't improve TU and Strength whereas his reactions and FA are the best among the men: 38 and 56 (everyone starts at 30 and 40 by the Bad Rookies difficulty setting). I also noticed such tendencies in EU, I had a guy with maxed Reactions (around 100) with still 67(!) TU and a guy with around 40 Reactions and 20 FA improvement and max TU (80) with still 4(!) Health improvement.
I also read on the same page "Promotions for rank above rookie are given out globally. That is, after any mission by any individual base, all soldiers from all bases become eligible for promotion... IF, and only if, someone obtained any combat experience." I must add to the condition (IF, and only if) that a killed officer may also trigger a set of promotion without any experience gain.
§ I read "Mutual surprise. If X-COM and alien units spot each other simultaneously, the aliens will not fire first," and "Aliens also benefit from mutual surprise. However, an X-COM unit being tracked by aliens' "intelligence" is already visible, thus cannot trigger the not-visible to visible transition that allows mutual surprise." Then it seems the aliens always
know where your soldiers are! Properly speaking, such as mutual surprise doesn't exist in the game. It is just a bug. When you sight an enemy unit by entering its range or line of sight, the program doesn't start the opportunity shot calculation subroutine but starts the "Put the Alien's Image on Screen" subroutine and forgets the other subroutine. This never happens to the alien side because your soldiers are always on screen in enemy turns. Dear wikipage editors, you put this on the wrong section. It should be put in the Known Bugs and Battlescape Exploits sections. You can place a soldier facing a door, he opens fire at the alien opening the door if he has enough Reactions and TU left. However, such a trap works better if you place the man by the door to open fire at the alien opening the door AND going through it because aliens' side armor is usually thinner.
I also noticed an odd thing. You wrote: "Will never trigger reaction shots: Turning in place," and this is correct, however, sometimes it seems as if aliens' turning in place also triggered reaction fire because I see some of my soldiers shoot when the alien, after having come through a door, turns towards my soldiers. I guess the alien wanted to walk
back because it didn't have enough TU to shoot but as it started to turn back in the direction of the door (essential for animation) it sighted my soldiers so it spent the TU for walk (4 TU) not for the turn to the L/R (2 TU) and the program took the move for a walk and started reaction fire. It should have been a mutual surprise case but as my soldiers were on screen already, the alien brought reaction shots. Mutual surprise doesn't exist in the two X-COM games; a variety of bugs, that is what exists. I read "TFTD, Terror From The Deep, X-Com, XCOM, et. al. originally developed by some very fine people. Originally distributed by Microprose. Now? Who knows." Calling the developers very fine people
is an open insult to decent game developers regarding game development. I can believe those are very fine at cooking, car driving, or playing the guitar but NOT game development. The two X-COM games are very fine games because the genre itself and the theme itself are very interesting but their coders and designers bungled them almost everywhere the games can be bungled. They just luckily touched a thing essentially bringing success. It happens. This is called virtue
. They are virtuous
, I agree.
§ It is not a bug but it proves that the geoscape wasn't programmed to be foolproof. If you avoid combat and just make the X-COM craft follow the UFO (alien sub), then you can still click on the craft's dot to command otherwise after that, for example move to a waypoint. The craft moves toward the waypoint and you can click on the craft's combat screen icon to fight or leave the target. Then the craft will return to base and the waypoint stays on the globe unerased until next new game. Such a haunting waypoint can be a real dirt on the geoscape. So don't be a fool by doing unexpected things in X-COM, especially in X-COM.
