Match
A player who has cleared this content before takes it: exploration is route knowledge, and the route is most of the time.
Sweep
Chests, puzzles and collectibles are cleared in one pass rather than several, banking the rewards as they go.

All reviews →Amazing service! They took a custom request from me for the game Marathon and completed it extremely fast!
What you get
Codex challenges are the part of a season that survives the reset in memory rather than on the account, and they ask for specific conditions rather than hours — which is exactly why they stall.
Completed on your account by hand, with the rewards left where the game puts them.
Say which entries are blocking you; a single stubborn challenge is a much smaller order than the full codex.
What we need from you
- Account access required during the service — the login is shared in the order chat and changed back when the order closes
