The Fortnite map you’re describing is likely Secret Red vs Blue , since a video walkthrough says you can go to a room, disable build reset, and then destroy builds for XP there.

What it does

That clip says players get XP for every build they destroy, and it even gives a map code: 2673-7442-3940. Another post describes the same kind of map behavior more generally: destroy builds, get XP, and repeat.

Extra context

These XP maps can change or get patched, so the exact setup may not work forever. If you want a broader list of current XP maps, guides from May and April 2026 are also tracking active options.

TL;DR

The specific “destroy builds for XP” map is most likely Secret Red vs Blue with code 2673-7442-3940.
