- Banned in Germany: Whilst the first two games aren't exactly banned, Microsoft never submitted them to the USK since they wouldn't get the 16+ rating they were aiming for. Finally averted with Gears of War 3.
- B-Team Sequel: Gears of War: Judgment is the first title developed by People Can Fly rather than Epic.
- Channel Hop: The series is now developed by The Coalition since 2016, following the 2014 acquisition of the IP from Epic Games, who sold it outright so they can move on to other ventures.
- Crossdressing Voices: The Berserkers are actually voiced by Dee Bradley Baker.
- Executive Meddling: Microsoft pushing the release date of Gears of War 3 back five whole months from April 2011 to September 2011. It is arguably a positive example of meddling, members of Epic Games have said the delayed release gave them more time to refine the game, they would not have done a multiplayer beta if this had been released as scheduled and that helped polish everything to a spit shine.
- Germans Love David Hasselhoff: For whatever reason, the games have a massive following in Mexico and South America.
- I Knew It!: Before Gears of War 4 was released, many fans jokingly speculated that Baird was the one who created the DeeBees that the reformed COG uses since they shared the same initials as him. The campaign proved the fans right by revealing that over the 25 year Time Skip, Baird became a Famed in Story world-renowned industrialist who, being the resident Gadgeteer Genius of the COG, is indeed the creator of the DeeBees.
- The Other Darrin: Jace goes from having an Australian-sounding voice in his cameo in Gears of War 2 to being played by Michael B. Jordan in Gears of War 3.
- The Other Marty: As shown in this interview, Christopher Sabat recorded lines for Marcus Fenix in Gears of War 2 during the 200708 Writers Guild of America strike that affected the LA unions (thus having the game be moved over to Texas for voice recording due to its non-union environment, effectively bypassing the union-related issues) note until the game was moved back to LA to be recorded once the strike ended.
- Sleeper Hit: Epic was plainly dedicated to the Unreal series in 2006, with Unreal Championship 2: The Liandri Conflict being released as a closure title for the original Xbox, and the then upcoming Unreal Tournament III (then Unreal Tournament 2007) having been announced at the same time. But Epic was also working on this title as well, to little fanfare during development. It eventually launched with (and became the Killer App for) the then just-released Xbox 360 as well as popularizing cover-based shooters and pulling Epic out of their "only Unreal games" stigma by giving it another Cash Cow Franchise.
- Throw It In!: A possible JD line after killing a Sentinel ("Sentinel? More like send it to hell! Right, guys? No? Too much battle? Too much battle, too much battle, we'll do it later.") was an ad-lib that not even voice actor Liam McIntyre thought made it in. He's also amused that this line singlehandedly brought the concept of hell to the Gears universe.
- What Could Have Been: The series staple, the Lancer/Chainsaw Bayonet, was on the edge of whether it was going to be actually included in the game. It wasn't until they devised the design of it being integrated into the grip that they devised a semi-plausible chainsaw mounted assault rifle. Somewhere, a group of "Stop Having Fun" Guys who want everyone to only use the Gnasher are cursing their rotten luck.
- The Locust were supposed to have an entirely different type of the Triple Punch execution in which they would rip the enemy's arm off, then beat their face with it. It was cut out due to timing issues in Gears of War 2, but made its debut in Gears of War 3, giving them a unique execution from the COG.
- Baird and Cole's roles were originally reversed, with Baird being the one who was a former sports star.
- Epic Games had originally planned to allow players to choose the gender of Dom, potentially making him into the female Dominique, but the idea was scrapped, as having two genders for Dom would've drastically increased the length of the script and limited the budget, so female characters wouldn't become playable until Gears of War 3.
- The Rousing Speech given in the beginning of Gears of War 2 was originally supposed to be narrated by Hoffman, but he lost out when the developers created Prescott, as they felt the speech was better suited for him instead.
- Originally, Hoffman was supposed to die in Gears of War 3. He was supposed to come with Delta to acquire the submarine instead of Dizzy and would've died protecting it while it sailed off to Azura. However, Karen Traviss considered Hoffman one of the few people in the universe who had a historical perspective on the series (he could talk about the world before the war) and didn't want to lose him as a narrative vehicle for the books.
- When playing through Beast Mode in Gears of War 3, one will notice that there are 5 empty spaces in the Locust selection interface. Indeed, there were originally 20 playable creatures to choose from in the mode. Early beta footage showed that the Grenadier Elite was playable; most likely cut for playing identically to the Savage Grenadier, so it was unnecessary to include both grenadiers. The footage also showed that Grinders were originally playable as well; most likely cut for being too easy to sit in the back of the maps and pick off humans from a distance since Beast encourages players to get close to the action. Also, Grinders don't possess melee attacks, so they would have no reliable way to kill Hero units and Onyx Guards. In addition, Reavers were also playable as well. They were stated to have been cut due to the developers having issues with them fitting on the smaller and indoor maps like Checkout and Rustlung. However, since Reavers are very large, it was also probably overpowered since you could potentially just launch rockets over the scenery to get easy kills while bypassing the fortifications. Another minor one, but the Armored Kantus was also shown Dual Wielding Boltok pistols in beta footage, but was changed to dual Gorgons. Sadly, it is unknown what the other 2 cut creatures were.
- Players hacking into an FPS made by Epic Games Shanghai, Passion Leading Army, discovered scripts of GOW 2 that indicated the developement had already went into advanced stages.
- There was originally going to be a movie trilogy based on the game series, with Marcus Fenix as the lead character.
- The Locust were originally going to be called the Geist, and Epic took such a strong liking to the name they even considered naming their new IP after it. In the middle of development, during 2003's E3, Nintendo announced their own game called Geist, and thus sinking that opportunity.
