Progressing through levels in Timeline Up requires strategic play, skill upgrades, and the effective use of your warriors. As you advance, you’ll encounter gates that boost your firepower when passed through. Strengthening your fire abilities through these gates is crucial for overcoming challenges in each level.

To further enhance your performance, you can invest in upgrades for both your skills and your warriors. The stronger your warriors are, the more efficiently they can face and overcome obstacles. This makes completing levels significantly easier and enables smoother progression through the game.

At the end of each level, specific obstacles block your path to the final gate. To reach the next Era, you must destroy these obstacles by shooting at them. Clearing these final challenges unlocks the gate, allowing you to advance to the next Era and explore new parts of the Timeline.
