How to get Mercenary in SCP Tower Defense

The Mercenary tower is obtained from the game’s tower/store system rather than from a random drop. Based on the game wiki, tower-related currency is used to buy or evolve towers, and codes can also give rewards that help you afford unlocks faster.

What to do

  1. Open SCP Tower Defense on Roblox.
  2. Check the Tower Store or any unlock menu for Mercenary.
  3. Earn the currency needed by playing modes, because the wiki says players can get currency by winning or even losing modes.
  1. Also redeem any active codes from the Daily Rewards & Codes menu to get coins, shards, or tokens that may help with the purchase.
  1. If Mercenary is tied to a special skin or badge reward on a map or mode, you may need to clear that specific challenge first. The wiki’s Site Badlands page shows that some rewards in this game are linked to mode/map completions.

Useful context

The game’s code pages and store page show that rewards and currencies can include coins, shards, and tokens , which are the usual route for unlocking or upgrading content.

If you are trying to unlock Mercenary specifically and it still does not appear, it is likely locked behind progression, a mode requirement, or a limited-time reward path.

Fastest approach

  • Redeem the latest codes first.
  • Farm the easiest mode you can reliably finish.
  • Recheck the tower/store unlocks after each currency gain.
  • Look for any challenge badge or map completion requirement attached to Mercenary.

TL;DR: Mercenary is most likely unlocked through the tower/store system using in-game currency, with codes and mode rewards helping you get there faster.
