How Gears of War: E-Day Solved Its Own Chainsaw Gun Problem

The Chainsaw Lancer — the assault rifle with a roaring chainsaw bolted underneath — is the weapon most players picture when they think of Gears of War. The upcoming prequel, Gears of War: E-Day, had a lore problem: according to established canon, the weapon was not invented until a year after Emergence Day, the catastrophic event the game is set during. So how do you ship a Gears game without its signature gun?

The Coalition, the Xbox-owned studio developing the title, solved it by introducing a Prototype Lancer — an earlier version of the weapon that existed around the time of Emergence Day. In the game, the Chainsaw Lancer is not a factory product handed to soldiers. It is born on the battlefield, kit-bashed from a prototype on the front lines (Xbox Wire). Players who watched the first reveal trailer back in 2024 may have noticed Marcus Fenix wielding an MK 1 Lancer with a detachable bayonet, not the chainsaw-equipped model the series is known for (Xbox Wire). The bayonet version is the standard-issue rifle of the era. The chainsaw attachment is the improvisation.

The inspiration for that improvisation comes from a place some fans might not expect: a novel. The 2008 book Gears of War: The Aspho Fields by Karen Traviss helped shape the story of E-Day, according to creative director Matt Searcy, who said the team aims to respect established canon wherever possible — including lifting moments and dialogue directly from the books (GameSpot). In the novel, Gear soldier Tai Kaliso uses a power saw in combat, which inspires the creation of the chainsaw attachment for Lancer rifles. E-Day includes a scene where Tai uses a chainsaw in a grocery store to kill a Locust enemy, pulled from the book with its original dialogue intact.

The Aspho Fields also covers the Battle of Aspho Fields, in which Dominic Santiago's brother Carlos dies — an event that sits at the emotional centre of the novel and feeds into the broader story E-Day draws from.

For players who care about how the gun feels, not just where it came from, the Prototype Lancer has a higher rate of fire and a deeper magazine than recent Lancer models in the series, making it a well-rounded rifle in its own right (Gears of War official site). Xbox Game Studios has also released a 1:1 scale Prototype Lancer replica as a display piece (Gamespress), and the game's Collector's Edition features Marcus holding the Prototype Chainsaw Lancer that gets its origin story in the game (Xbox Wire). Themed Xbox controllers with crossed Lancers and skull detailing are also available (Xbox Wire).

Gears of War: E-Day launches on 6 October for Xbox Series X|S and PC.

For a franchise built on a weapon that became an icon, building a whole origin story for it — rather than quietly ignoring the timeline — is the kind of detail that turns a prequel from a nostalgia exercise into something that adds to the canon instead of bending it.
