The Hollow Tower Defense Simulator: Badge and Tickets

In The Hollow, "tower defense simulator" isn't a mode inside the Hollow hub itself — it's a stop in the separate Roblox game Tower Defense Simulator. The Hollow's Roblox page explains that event quests run in the hub and in "participating experiences," which is where this stop fits. Two player walkthroughs of the event show the same short loop: leave the hub, play one Night One round on Easy, win it, and return with a badge and event currency.

What the stop actually gives you

Players report the reward as a badge (one of the event's collectible emblems) plus 20 event currency, which the recordings call "tickets" in one video and "20 points" in another. That currency is spent back in the main Hollow area on event items, so the round is effectively a chore you repeat to fund the shop.

Both recordings are ordinary player footage with no version number attached, so treat the 20-unit figure and the naming as player-reported rather than a fixed number that can't change.

How the round plays out

The sequence below is what the two walkthroughs show, not an official step list:

1. From the Hollow hub, launch into Tower Defense Simulator. One video notes a cinematic plays first and becomes skippable after a moment.
2. At the selection screen, choose Night One and press play.
3. Pick Easy, then choose solo or a group. One player went solo to keep it simple.
4. The event hands you a free tactical loadout, so you don't need your own towers or a deep knowledge of the game. Both players took the provided loadout.
5. Place towers along the path, then upgrade them as waves clear — cash comes from defeating enemies, so upgrades snowball.
6. Clear the waves. One player's run was 15 waves with a boss at the end; he estimated the whole thing at under 10 minutes.
7. Win the round, then claim the reward prompt. One video shows the badge popping and a confirm screen for 20 tickets, after which the player returned to the Hollow to spend them.

Player-reported controls and tips

In the more detailed playthrough, the author used ability keys during the boss fight: B for an attack-speed buff from a commander-type unit, F for a freezing grenade from the freezer unit, H to fire a tank missile, and X to sell a tower. These are that player's own bindings on his setup — check your own layout rather than assuming they match.

A few habits those runs suggest:

• Upgrade existing towers before flooding the map with new ones; the players who struggled were the ones spreading cash thin late.
• Selling towers mid-round returns cash you can redirect into your boss-killers. The winning run sold off several towers on the final wave.
• Keep a slowing unit near the choke point; both videos lean on a freezer-type unit to hold enemies in range.

What the material doesn't settle

Neither recording states a game build or date within the event, and the official Hollow page lists the event's badges and opening time (October 22, 2pm PT) but no step-by-step instructions for individual stops. If a reward prompt doesn't appear after a win, the safest checks are that the full round finished and that any confirm screen was accepted — beyond that, the footage doesn't show a failure case to compare against.

FAQ

What is the tower defense simulator in The Hollow?

It's the event's stop inside the Roblox game Tower Defense Simulator, one of the "participating experiences" the Hollow page mentions. You play a single event-modified Night One round there and bring the reward back to the hub.

Do I need to be good at Tower Defense Simulator to finish it?

Both players stress that the event gives you a free loadout to use, and one explicitly says not to worry if you've never played. Place towers, upgrade them as you earn cash, and play solo if you want a quieter run.

How many tickets does the tower defense simulator stop give?

Players show 20 units of event currency on the reward screen, though one video's title calls them "20 candies" and its narration says "points." The recordings don't state a version, so the exact label may differ from what you see.

How long does the round take?

One player counted 15 waves plus a boss and guessed under 10 minutes in total. That's an estimate from a single solo run on Easy, not a measured time.
