Bomb Farm Walkthrough: Stage-by-Stage Progression Through 600 Stages

There is no verified stage-by-stage walkthrough for Bomb Farm yet, and the '600 stages' total itself has not been confirmed by any official or community source we could check. What is confirmed is that stages use a chapter-stage numbering format such as 5-19, that a difficulty tier called Normal exists, and that clearing stage 5-19 on Normal is the current gate for unlocking the Steam Market trading function. This guide lays out every progression fact that can actually be traced to the Steam store page or the official Steam Community, and clearly marks what is still unknown.

What Is Confirmed About Bomb Farm's Stage Structure

Bomb Farm (Steam AppID 4892010, developed and published by Stream On, released 28 August 2026, Windows only) is a free-to-play idle RPG in which your bomber squadron destroys rocks in the mine, gathers resources, and hunts for rare items while you are away. Stages are numbered in a chapter-stage format: community threads refer to '5-19', meaning chapter 5, stage 19. Those same threads specify '5-19 Normal', which confirms that at least one difficulty tier named Normal exists.

Beyond that, the stage map is undocumented. The figure of 600 total stages, the number of chapters, how many stages each chapter contains, where boss stages sit, and whether Hard or other tiers exist above Normal all appear in nowhere we could verify. Treat any site listing per-stage rewards, key drops, or timed X-10 gates with caution until Stream On publishes official numbers or the Steam Guides section fills in. Because the game is playable at your own pace with Save Anytime and Steam Cloud support, you lose nothing by progressing slowly and letting the idle loop do the work.

The One Milestone That Matters: Stage 5-19 Normal Unlocks the Market

The single progression checkpoint with real evidence behind it is stage 5-19 on Normal. Multiple Steam Community threads ('Activating the market function (5-19)', 'Did the Market requirement change to 5-19 Normal?', 'market requirement change again') confirm that clearing this stage is what activates the in-game market function, which lets you trade items with other players on the Steam Market as advertised on the store page. The threads also make clear this requirement was changed in an update within the first two weeks after release, so the gate was different before and could shift again.

For a new player, this means the early game has one clear objective: push through chapters 1 to 5 on Normal until 5-19 is cleared. Everything you build before then, from hero roster to gear upgrades, should serve that push. Once the market opens, sealed drops and revealed rare items gain a second use as tradeable goods, which changes how you value duplicates. Note that using the Steam Market at all also requires your Steam account to meet Valve's usual conditions, such as Steam Guard mobile authentication, and Steam takes a 5% fee on each sale plus any publisher fee.

Early Progression: Build the Bomber Squadron Around Four Roles

Your power in every stage comes from heroes, and the store page confirms four hero roles: Attacker, Support, Collector, and Specialist. Each hero has unique attributes and abilities. There are 20 abilities in the game, and each one can be upgraded from level 1 to level 10. In the earliest stages, spreading upgrades thinly across many abilities is the usual trap in idle RPGs; the confirmed structure of 20 abilities with 10 levels each rewards picking a few and taking them deep, though the specific ability names and effects have not been documented in any source.

The second confirmed early system is team rotation. You can switch between three teams to keep the mine running nonstop. Practically, that means you should fill all three slots as soon as you have enough heroes rather than perfecting one team, because idle income depends on the mine never sitting empty. A reasonable reading of the four roles is to give each team at least one Attacker for rock destruction and one Collector for resource pickup, then slot Support and Specialist heroes where you have them, but role-by-role stat details remain unverified.

Mid-Game Power: Gear Upgrades, Sealed Drops, and the Skill Tree

Once your squadron is set, the store page identifies equipment and epic drops as your main source of power. Drops arrive as sealed items that must be revealed before you know what you got. Equipment can be upgraded from +0 to +15, and fusing duplicate items grants stars. The developer also describes 'chasing the perfect attribute', which confirms that gear rolls attributes and that re-rolling or re-farming for better attributes is an intended long-term loop. Exact upgrade costs, star caps, and attribute pools are not published anywhere we could verify.

In parallel, Bomb Farm has a large skill tree that applies to your entire team, described as inspired by the style of Path of Exile and containing dozens of nodes. Path of Exile's tree is a web of nodes where you choose your own path, so expect Bomb Farm's version to reward committing to a direction rather than grabbing scattered nodes. Since the tree buffs the whole team, it is the best place to invest once individual hero abilities start hitting diminishing returns. Node names and recommended paths have not been documented by any source yet.

Settings and Free Rewards That Speed Up Progression

Bomb Farm has an auto-advance setting that moves you to the next map automatically. A Portuguese-language community thread describes a player who turned this off ('desativei para passar de mapa automatico') and then asked how to turn it back on, so the toggle exists and can be disabled. The official English name of the setting and its menu location are not confirmed; if you want steady stage progress while idle, keep it on, and if you want to farm a particular map, turn it off.

Free resources are also available through the Friend Code system. The 'Friends code mass share' thread is the busiest topic in the General Discussions board with 122 replies, and a separate thread titled 'Free loot with friend code' confirms that sharing and entering codes grants rewards. Threads also reference an 'EXTRA CODE', which suggests redeemable bonus codes exist, though their contents are unconfirmed. Entering codes early is cheap and helps the chapters 1-5 push toward the market unlock.

Known Issues and Cautions Before You Commit

Bomb Farm depends on online servers. Community threads from early September 2026 ('Jogo off para mais alguém?', '什么都没了？') report periods where players could not log in or found their progress temporarily missing. Because the game is idle-based, a server outage stalls your progression, so do not assume the mine is running during a reported outage.

The game includes in-app purchases, including a VIP Pass. After the update that changed the market requirement, some VIP holders reported that their market was locked and that they could no longer sell items. There is a public VIP refund policy, but some players say it was not honored. The community also contains refund demands, a claim of being banned after asking questions, and a thread accusing the economy of being pyramid-like. These are player opinions, not verified facts, but they are worth reading before spending money.
