To complete the Tower Defense Simulator quest in The Hollow, win one match of Night 1 on Easy, then rejoin The Hollow and redeem the badge for tickets. The Hollow is a limited-time Halloween event hub on Roblox, and its quests link out to other games. The quest asks only for that one win, but a few menu steps are easy to miss.
| Requirement | What to choose |
|---|---|
| Where to start | The ticket counter in The Hollow, then Visit Games |
| Night | Night 1, the only night open at the start |
| Difficulty | Easy |
| Squad size | Any of Solo, Duo, Trio, or Quad |
| Loadout | Any ready-made preset |
| Win condition | Survive all 15 waves and defeat the wave 15 boss, Penumbras |
| Reward | A Tower Defense Simulator badge, redeemed for tickets in The Hollow |
Start the Tower Defense Simulator Quest From Visit Games
Begin in The Hollow, because that's where the quest and its reward are handled. Visit Games is the route that takes you from the hub into Tower Defense Simulator.
- Click the ticket counter in the lower-left corner. The LITTLE SHOP OF TERROR panel opens.
- Select Visit Games.
- Click the Tower Defense Simulator tile.
- Press Let's go! to teleport.
- In the lobby, press Let’s Go! on the Solar Requiem welcome pop-up. You can skip the cutscene that follows if you like.
Pick Night 1, Easy, a Squad Size, and a Loadout
Night 1 is the only night open at the start, and the badge is for Night 1 on Easy, so those two choices are fixed. The squad size and loadout are up to you, since the badge doesn't name either one.
- Press PLAY in the lobby.
- Select Night 1.
- On Choose a Difficulty, select Easy.
- On Choose a Squad Size, pick Solo, Duo, Trio, or Quad.
- On Choose Your Loadout, pick a ready-made preset.
A brand-new account can finish the run with a ready-made loadout, so you don't need a large tower collection. Tactician, Experimental, and Crowd Control are among the presets listed as usable on a new account, so they're a good place to start.
Survive All 15 Waves to Defeat Penumbras
You win by getting through the whole match, so your job is to keep your base standing from the first wave to the last. Place towers on open ground beside the enemy path. Towers can't go on the path or the stairs.
Wave 15 brings the boss, Penumbras, and you have to defeat it to win. When you do, a screen labeled TRIUMPH! appears. That's the sign the match ended in a win, and the point where you can head back to The Hollow.
Redeem the Tower Defense Simulator Badge for Tickets
The match itself doesn't hand over tickets. The win unlocks a Tower Defense Simulator badge, and The Hollow converts that badge into tickets, so you need to rejoin the hub to collect them.
- Rejoin The Hollow.
- Click Got it! to dismiss the How to Play card.
- In the REDEEM BADGES panel, find the Solar Requiem: Night I (Easy) badge.
- Check the ticket amount the panel shows for it.
- Click Confirm.
- Look at the ticket counter in the lower-left corner. It should rise by the amount the panel showed.
