What TRENCH: DECAY is

TRENCH: DECAY is a WW1-inspired, squad-based PvE first-person shooter on Roblox built by studio rook, an independent solo developer. You push through muddy trenches with a small team, survive relentless enemy waves, and earn Medals and Enlisted crates that unlock melee and firearm gear. It is still in Early Beta, so mechanics and codes change often — sometimes day to day. The game was previously called TRENCH: WW1, which is why several code sites still list it under that older name.

The other game

What TRENCHES is

TRENCHES is a separate Roblox title by DYNAMIC STUDIOS. Public listings describe it as a large-scale, objective-based WW1 shooter — commonly reported as a 25v25 team experience where you pick a class and level up historically-inspired weaponry across the frontline. It is a much larger, more established game with its own community, its own updates, and its own set of promo codes. None of that carries over to TRENCH: DECAY. The same name confusion shows up with other titles too — see how TRENCH: DECAY compares to Helldivers 2.

Why the codes never cross over

Every Roblox game validates promo codes against its own backend. Because TRENCH: DECAY and TRENCHES are built and hosted by different studios, a code from one simply does not exist in the other and will return an error. If a code you found is not working, the most common reason is that it belongs to the wrong game. For TRENCH: DECAY, always use the current, verified list on our Codes page.
