Into the Breach Beginner Guide: Read threats before choosing an attack

Before choosing an attack in Into the Breach, inspect what will be hit if you end the turn. Start with threatened buildings and mission objectives, then check your mechs. This gives each action a job before the most tempting target draws your attention away.

Enemy attacks are telegraphed, and civilian buildings supply the power your mechs depend on. Subset Games also warns that your own fire can harm those buildings. The preview therefore matters on both sides of an attack. Official game overview, developer's store description.

Make a short threat list

Inspect the marked attacks and the current mission objective. A threat to a stationary building needs a different response from an attack aimed at a mech that can move away. Check the affected squares and any movement restrictions before deciding which problems need a weapon.

Keep the list concrete: a building on the left, an objective near the center, a mech in an attack line. You can then compare each threat with the units able to reach it.

Plan the turn before spending the easiest action

Look for the threat with the fewest possible answers. Suppose two attacks need attention, but only one mech can reach the first. Reserve that mech for the first threat while checking whether the others can handle the second. This hypothetical example is about assigning actions; it assumes no particular squad or mission.

Preview the entire sequence before committing an easy attack. Using a versatile mech too early can leave a distant threat without an answer, even though the first attack looked efficient on its own.

Compare the outcome with the objective

Read the weapon's full effect. Check damage, any displacement and the attacks that will remain afterward. An action can solve an immediate threat without killing its source, provided the resulting preview shows that the protected target is safe.

Conversely, removing an enemy does little good if the same attack damages a building you needed to protect. Judge the resulting board and mission condition together. After each action, check whether the rest of your planned sequence still works.

Keep collateral damage in the calculation

Follow the effect across every affected square, including where a displaced unit would end up. Read the current weapon text when upgrades or equipment have changed; a remembered value from an earlier run may no longer apply.

If the preview differs from your expectation, resolve that difference before confirming. You may have missed an effect or an occupied square. The turn-based format gives you time to inspect it.

Use a final check before ending the turn

Return to the attacks you identified at the start. Are any still aimed at a protected target? Did moving a unit create a new collision or leave a mission objective exposed? Check the updated board rather than the arrangement you remember planning around.

Learn from one decision after a mission

When a turn goes badly, name the constraint you missed: reach, action order, collateral damage or a mission condition. For example, noticing that you spent the only mech able to reach a far threat gives you a precise check for the next mission. It is a more useful lesson than judging the run by the final result alone.
