* Why is it the old Lancers are inaccurate and slow firing while the new one is accurate, faster firing, and chews through ammo quicker? It's hard to see how one grew into the other until realizing the retro lancer was an offensive weapon, used for constantly redeploying closer to the enemy and charging forward. Whereas with the modern Lancer they've fallen back to Jacinto and needed something that could function while holding a single location.
* The Locust Horde is by no means primitive technologically, instead using OrganicTechnology as counterparts for COG developments. The COG use more familiar machinery, instead running on the gasoline-like [[GreenRocks Imulsion.]] However, this discrepancy in technological development makes sense lore-wise as well. Humans harness Imulsion, [[spoiler: which is actually what's killing the planet, without knowing the truth behind it]]. The Locust, developing underground and living next to the stuff,[[spoiler: would have discovered its danger long ago]], prompting their development of biotechnology (which would never need Imulsion).
* Why is it that the locust drones are smaller and weaker than the females of their species, the Berserkers? In reptiles, the females are always bigger than the males, and Locust are a species of underground-dwelling lizard men.
* In ''Gears of War 4'', the Deadeye [=DeeBees=] are pretty lousy shots, even on Insane difficulty, compared to what human players can do using sniper rifles. They often miss badly and very rarely land headshots. Since the Shepherds never had much of a job in combat other than to suppress/detain possibly unarmed civilians, they wouldn't need to be totally accurate in order to be effective. If some average Joe is causing trouble, they could simply fire a bullet or two in his general vicinity, and he'll probably just take off.
* In Horde 3.0 (featured in ''Gears of War 4''), the player can use decoys that look like humans and can be used to distract the enemy, fooling them into thinking the decoys are actual living humans. Decoys draw the attention of the Swarm far better than they draw the attention of the mechanical [=DeeBees=]. It makes sense, because robots don't rely on sight as much as an organic creature; they can detect vital signs (heartbeat, breathing, body heat, etc.) that an inanimate object wouldn't have.
* The fate of [[spoiler: Sofia Hendrik]] is probably... ugh.
* By ''Gears of War'' 4, humanity, or more specifically [[spoiler: Baird]], has created the android race of [=DeeBees=] to assist the remaining human population in labor and protection from outside forces. However, if you play through Horde, you'll notice that the [=DeeBees=] aren't very interested in attacking the Swarm. Why exactly is that? Well, if you played the campaign, you'll see how the [=DeeBees=] you fight are colored blue and they're only really attacking you because you are breaching unauthorized areas and JD and Del are traitors to the organization they serve. Towards the end of the campaign, a Pouncer shoots one of Jinn's avatars, causing it to turn red and nearly strangle JD to death. [[OhCrap Now, what color were the robots in Horde again]]? That's why the [=DeeBees=] don't attack the Swarm: they '''hacked''' them. They took humanity's biggest allies and turned them into mindless killing machines that can cause just as much destruction to humanity as the Swarm can. Imagine if they were able to capture huge warehouses full of offline [=DeeBees=] and sic them on humanity with them being none the wiser. Imagine standing behind your robot army, fully expecting them to annihilate the creatures threatening your species, but for some reason, they turn their guns on YOU and speak about how "you will be dealt with harshly." The Swarm could easily add another faction to their army, turning a war between man and beast into a CurbStompBattle in their favor...
