The single most important habit in BioShock Infinite is consistency — the systems reward players who learn the core loop before chasing shortcuts, and almost every wall you hit is a sign to practice one mechanic, not to abandon the run.

Priority checklist (do these first):

• Keep moving — a stationary target is an easy target.
• Manage ammo; melee or sidearm when low rather than reloading in the open.
• Use the environment; explosive barrels are free damage.
• Finish on the hardest setting only after you know every encounter.
• Learn grenade arcs for the two chokepoints you fight most.

Common beginner mistake: The error that gets you killed in BioShock Infinite is reloading in the open; the reload animation is your most vulnerable window.

3Step-by-Step Walkthrough

Follow this order and you will clear BioShock Infinite on PS3 without grinding for hours. Each step builds on the last, so do not skip ahead — the early habits make the late game trivial.

1. Keep moving — a stationary target is an easy target.
2. Manage ammo; melee or sidearm when low rather than reloading in the open.
3. Use the environment; explosive barrels are free damage.
4. Finish on the hardest setting only after you know every encounter.
5. Learn grenade arcs for the two chokepoints you fight most.
6. Prioritize the heaviest enemy first to reduce incoming damage.
7. Save special weapons for vehicle or boss phases.
8. Upgrade mobility early so you can escape bad engagements.
9. Replay a mission on easy to learn spawn patterns, then step up.

Once the campaign is done, replay on a harder setting or chase 100% completion; the systems you learned on the first run make the second feel completely different, and most BioShock Infinite players agree the post-game is where the real depth lives.
