Find the settings code box.

Launch this exact experience and select the cogwheel in the top-right corner. Enter one code in the Codes text box and select Redeem. Check the reward, then repeat.

Codes are listed by the source as available on 12 November. No expired list was reported at that check; this does not guarantee every code still works after an update. Keep the capitalization and remove extra spaces. An already claimed reward cannot normally be claimed a second time on the same account.

The Halloween rewards include event currency and may be especially sensitive to event changes. If a seasonal claim fails while other claims succeed, check Pixel TD’s announcements rather than buying currency to try to repair the code.

Use the rewards to fix one squad problem.

Start in Normal story mode and learn placement, upgrades and active abilities before moving to Nightmare or Legend. Spend the first session observing where your defenses fail: enemies leaking through, a costly unit placed too late, or a boss surviving your upgrades.

Redeem the codes before making summons so you know your available Gems. Keep Trait Rerolls and Stat Rerolls for a unit you intend to use; a temporary starting unit may not justify spending your whole stock. A summon or reroll does not promise a Mythic, Secret or Shiny result.

The official listing describes 50+ units and Mythic evolutions. Rarity alone is not enough to recommend a lineup: placement cost, range and the enemies you are facing all matter. We have not invented a complete unit tier list from the code page.

Choose the next mode deliberately.

Mode	What the official listing confirms
Story	Six worlds, beginning at Greenfield Outpost
Difficulty	Normal, Nightmare and Legend
Co-op raids	Up to four players; Rift Gate, Coral Cove and Eclipse Spire
Expedition	One squad across three worlds; choose a Relic after each win
Infinite & challenges	Infinite mode and rotating challenges

Establish a working story squad first. When joining co-op, agree on placement and upgrades instead of assuming another player will cover every leak. Expedition makes your initial squad choice more consequential because it must carry across three worlds.
