Fast answer
The answer before the background
The base Element TD 2 campaign has 28 missions. The paid Mazing Expansion adds a separate 14-mission Mazing campaign, so a walkthrough must state which campaign it covers. Named searches such as Absolute Knowledge, An Interesting Choice, Faster Than Light, Full Support, Legendary and Triad of Light refer to achievement or challenge goals whose exact text can change or depend on the installed DLC. Read the current Steam achievement description first, then design the run around its mode, difficulty, tower and completion constraints.
Campaign ledger
Do not mix base missions with Mazing missions
| Content | Verified scope | Access | Walkthrough rule |
|---|---|---|---|
| Base campaign | 28 missions on the current base-game store page | Included with Element TD 2 | State the mission and available unlocks before recommending towers. |
| Mazing campaign | 14 missions on the official DLC page | Requires base game plus Mazing Expansion | Include blocker placement and maze boundaries in every solution. |
| Steam achievements | Global achievement list tied to app 1018830 | Base and DLC entries can coexist | Read the live condition rather than an old search-result snippet. |
| Campaign replay | Stars and unlock progression affect available options | Uses the player's existing save | Explain whether the solution assumes later unlocks. |
Achievement method
Translate the condition into a testable checklist
- Copy the exact achievement name and description from the current Steam client, including difficulty, mode and DLC requirements.
- List every action that would invalidate the run, such as using the wrong tower family, taking too long or allowing a leak.
- Choose a campaign mission whose path and starting unlocks support the condition instead of forcing the achievement on a poor map.
- Separate completion from four-star optimization. A safe clear and a score route can require different spending.
- If the achievement fails to unlock, confirm online Steam status, DLC ownership and whether the run used a modified or unsupported mode before repeating it.
Save boundary
Reset progress only after preserving the current profile
A reset is not a normal first step for a stuck achievement. Steam Cloud can restore a state the player intended to replace, while deleting the wrong local data can remove campaign stars and unlocks. First capture the current settings, verify Cloud synchronization, and test the achievement on the existing profile or a supported in-game option.
Quest Meridian does not provide instructions for deleting opaque save folders. If a clean profile is necessary, use a documented in-game profile function or developer support guidance. Record the current build number and the exact achievement before contacting the community, because a condition can be patched while old walkthroughs remain indexed.
FAQ
Common questions
How many missions are in the Element TD 2 campaign?
The current base-game Steam page lists 28 missions.
Is the Mazing campaign included?
No. The official Mazing Expansion is paid DLC that requires the base game and adds its own 14-mission campaign.
Where should I check achievement conditions?
Use the current Steam achievement list and the in-client description. Treat an older guide as a strategy reference, not the controlling definition.
Can the campaign be played co-op?
The base game advertises single-player and co-op modes, but a specific campaign mission's co-op availability should be confirmed in the current mode selector rather than assumed from the store tag.
