Fireboy and Watergirl 1 The Forest Temple Steam achievements on AppID 5084260 are exactly two: Complete all the levels and Get all the green gems. Complete all the levels unlocks when the player finishes every Forest Temple level. Get all the green gems unlocks when the player collects every green gem across the Forest Temple chapter, and the green gems are a separate collectible from the diamonds; diamonds gate the level exit, while green gems feed the second Steam achievement. Specific Steam achievement icons, global completion percentages, and per-level green-gem counts beyond what the Steam store page lists are Not announced as of 2026-09-06.
The full Steam achievement list
The Steam store page for AppID 5084260 lists two Steam achievements for Fireboy and Watergirl 1 The Forest Temple. The first is Complete all the levels, which unlocks when the player finishes every Forest Temple level in the chapter. The second is Get all the green gems, which unlocks when the player collects every green gem across the Forest Temple chapter. These two achievements are the complete Steam achievement list for the standalone Steam release as of 2026-09-06; the Steam store page does not list any other achievement for this AppID. Specific achievement icons, unlock text, and global completion percentages beyond the names above are Not announced as of 2026-09-06. The earlier third-party descriptions that framed a single chapter-perfect achievement unlocked by collecting every diamond do not match the actual Steam achievement list, which is split into a level-completion achievement and a separate green-gem collection achievement.
Green gems are separate from diamonds
The Forest Temple chapter uses two different collectible types. Diamonds (cyan water-safe and red fire-safe gems) gate the per-level exit: the diamond counter must be full before the twin exit doors open. Green gems are a different collectible, do not affect the per-level diamond counter, and do not gate the level exit. Green gems exist to feed the second Steam achievement only. On every Forest Temple level where they appear, green gems sit in harder-to-reach nooks that are easy to skip during a level-clear run. A player who only chases diamonds will finish the chapter with a clean level-completion achievement but no green-gem achievement. The Forest Temple chapter from the 2009 Oslo Albet Flash original places green gems on a subset of levels rather than every level; the per-level green-gem count for the Steam release mirrors that 2009 baseline and is Not announced as a Steam-specific change as of 2026-09-06.
Where to find green gems in the Forest Temple chapter
The Forest Temple chapter from the 2009 Oslo Albet Flash original places green gems on specific levels rather than every level. A solo player hunting the Get all the green gems achievement should pair the chapter walkthrough with the diamonds and element-traps pages so they can plan a green-gem pass after the level-exit diamonds are already collected. The chapter walkthrough page describes the box-as-pressure-plate hold technique that lets a single character reach otherwise unreachable green-gem tiles. Players who want to combine the two achievements in one run should follow the solo pickup order on the chapter walkthrough: water-safe diamonds first with Watergirl, fire-safe diamonds second with Fireboy, then green gems last while the box-on-pressure-plate hold keeps the door open. The exact Forest Temple levels that contain green gems are tied to the 2009 Oslo Albet original level list and are visible in the Steam build once the level list is verified post-launch.
Strategy to unlock both achievements in one run
The fastest way to clear both Steam achievements on AppID 5084260 is to plan the run as three passes rather than one. Pass one: clear every Forest Temple level with the standard diamond quota to unlock Complete all the levels. Pass two: replay the levels that contain green gems and collect every green gem to unlock Get all the green gems. Pass three (optional): replay any level that contains a missed diamond for the chapter-perfect ending. Solo players should use the box-as-pressure-plate hold on every green-gem attempt, because most green gems sit on tiles that are only reachable through a simultaneous-button cooperative trigger that no single character can hold open. The Steam Cloud save support listed on the Steam store page keeps the diamond counter and the green-gem counter in sync across Steam clients, so the run can be resumed on a different machine without losing progress.
