Progress the game, then check the Workshop board
For ANOMALITH how to unlock side missions, the official answer is progression: side missions become available as you advance through the game. The Workshop board is the confirmed acceptance point for the early-purchase collaboration mission. That distinction matters because owning a bonus is not the same as immediately having its mission ready at the start of the game.
The official ANOMALITH Steam listing states the progression condition without naming an exact chapter or number of completed Dives. Use your current story objectives to advance, then revisit the board as features open rather than relying on an invented mission-count requirement.
Accept the collaboration mission when available
The Steam early-purchase information identifies the collaboration side mission as “Contradictory Otherworld Response,” made with the Lost Property Control Organization. Its listed acceptance point is the board in the Workshop.
A practical sequence is:
- Continue the story until side missions are introduced or become available.
- Visit the Workshop and inspect its board.
- Look for “Contradictory Otherworld Response” if your purchase includes that bonus.
- Complete the collaboration mission before expecting its associated reward claims.
- Return to the Workshop board for the collaboration costume and T-6407J probe skin.
These steps follow the official eligibility and reward wording. They do not establish the exact first story mission that opens the feature, and they do not mean every side mission in the game is a purchase bonus.
Keep mission rewards separate from material bonuses
The collaboration costume and probe skin are claimed from the board after the collaboration mission is completed. The early-purchase Development Materials Set works differently: the Steam listing says it is granted after the Shooting Range unlocks.
| Item or feature | Officially described condition |
|---|---|
| Side missions | Unlock as you progress through the game |
| Collaboration mission | Accepted from the Workshop board when available |
| Collaboration costume and T-6407J probe skin | Claimed from the board after completing that mission |
| Early-purchase Development Materials Set | Granted after unlocking the Shooting Range |
If you are checking a missing reward, first identify which row applies. Looking at the board before completing the mission will not satisfy its completion condition, while waiting for a costume to arrive with the material set mixes two different delivery paths.
Use side missions for more than item claims
The official ANOMALITH website describes side missions as a way to learn more about other characters' backgrounds and relationships. They are therefore part of the game's character information as well as a place where a specifically listed collaboration reward can be earned.
Check the individual objective and availability shown in your version. The registered official material does not provide a complete side-mission catalog, a universal reward table, or a verified troubleshooting fix for a mission that fails to appear. A progression condition should not be expanded into an unsupported claim about a broken save or a mandatory Deluxe upgrade.
FAQ
What unlocks side missions in ANOMALITH?
The official Steam listing says they unlock as the game progresses. It does not give a specific chapter or Dive count in that notice.
Where is the collaboration side mission accepted?
“Contradictory Otherworld Response” is accepted from the board in the Workshop when it is available to an eligible player.
When can I claim the collaboration costume and probe skin?
The official condition is completion of the collaboration side mission, followed by claiming the rewards from the Workshop board.
Does unlocking the Shooting Range unlock every side mission?
The official material uses that milestone for delivery of a material bonus. It separately says side missions open through progression; it does not equate the range milestone with every mission unlock.
