Two kinds of events show up in the sources, and they should stay separate.
Raids in the playthrough
UFO RAID messages tell the player to collect a ray gun from the hotspot. A later message says the UFO has gone. GOBLIN RAID is on screen with the map label SOUTH CONVEYOR at 13:26.
Cash on the HUD changes during parts of the recording. That does not prove a fixed raid payout. No reward table for either raid was readable.
The ray gun is a pickup named by the UFO message. Its damage, duration, and whether you keep it are not documented.
South Conveyor is a label seen during the Goblin raid. It is not confirmed as its own crater.
Halloween update schedule
A public event tracker, set to UTC, lists HALLOWEEN UPDATE as:
- Start: October 29, 2026, 10:45 PM UTC
- End: November 6, 2026, 4:55 AM UTC
- Description: spooky decor on the moon and in the lobby, plus Halloween-themed events, robots, and drones
Another writeup of the official page mentioned October 29 at 8:45 PM and did not name a time zone, and it did not describe the decor. Use the in-game timer if the two clocks disagree. The same tracker had no separate code attached to the event.
The official page also asks players to like and favorite the experience for updates. That request is not a redeemable reward.
What to do during the window
Check the moon and the lobby for the decor the schedule describes. Keep using the sell pad and the bay boards you already understand. Do not assume a Halloween robot uses a new price until that board says so.
