Recent findings (audit lane, verbatim)

Medic — The entry states 'the five starting soldier classes in Enemy Unknown are Assault, Heavy, Sniper, and Support' — this lists only four classes, not five, and incorrectly implies five starting classes; the correct starting classes are Assault, Heavy, Sniper, and

Medic — The 'DID YOU KNOW' section is cut off mid-sentence: 'in XCOM 2 the Speciali' — this is an incomplete statement, which is a factual inaccuracy due to truncation.

XCOM: Chimera Squad — The entry states the game takes place in 2039, but XCOM 2: War of the Chosen is set in 2035, so five years later would be 2040.

XCOM: Chimera Squad — The 'DID YOU KNOW' section claims Sid Meier personally developed the prototype for the interleaved turns mechanic, which is not true; the mechanic was developed by the Firaxis team.

Morale and Panic — The claim that panicked soldiers required a nearby high-morale soldier or commander using the 'panic' command to recover is incorrect; the 'panic' command was used to cause panic in enemies, not to recover allies.

Morale and Panic — The claim that panicked soldiers did not automatically recover after a few turns is inaccurate; they did automatically recover after a random number of turns (typically 1-3), unless they fled off the map.

Research Tree — In XCOM: Enemy Unknown and Enemy Within, labs provide a flat bonus to research speed (e.g., +20% per lab), not a multiplicative effect on research points generated by scientists.

Research Tree — In XCOM 2, the primary research resource is not a separate 'Science' resource; Intel is used for instant research or speeding up, while research progression uses scientists and research time.

Difficulty Scaling — In XCOM: Enemy Unknown, higher difficulty tiers do not introduce new alien archetypes or weapon types that are unavailable on lower difficulties; all alien types and weapons are present across all difficulty levels, just at different rates.

Difficulty Scaling — XCOM 2 does not have a squad morale system that affects combat effectiveness; morale was a mechanic in the original 1994 X-COM: UFO Defense, not in XCOM 2.

Sniper Rifle — The 'DID YOU KNOW' section lists only four classes (Assault, Support, Heavy) when it should list five, omitting the Sniper class itself, which is factually incomplete.

XCOM: Enemy Unknown — The story begins in March 2015, when a series of extraterrestrial objects land in a major Russian city. A squad of four soldiers is sent to investigate. — The game's first mission actually takes place in March 2015, but the landing site is in a major city in t

XCOM: Enemy Unknown — The squad finds a small, alien creature mind-controlling Russian soldiers. — The soldiers being mind-controlled are not specifically identified as Russian in the game's opening mission; they are generic human soldiers, and the location is not Russia.

The World Map — The ADVENT Barrier is described as a physical or energy barrier encircling the entire planet, but in XCOM 2 canon it is a large wall-like structure on Earth's surface, not a planetary ring or cage.

The World Map — The entry states that in XCOM 2, some alien activity is obscured or misreported as a general mechanic, but the base game does not have systematic obscuring or misreporting of alien activity on the world map.
