The strategy is pretty much the same as one player any%: keep "walking" and kill all the 16 enemies fast on the end level

What's different?

• screen scrolls base on the player most at the top. if both are exactly side by side the screen slowly scrolls
• each enemies shot 2 bullets, one for each players
• hostage bonus counter is common for both, it resets when one player die
• dropping dynamite would depend on the player most of the top

General strat

In order to most bullets and grenade, it's best if both player are at the same vertical line. Each player needs to pay attention to the other player. To save time, players would be on opposite side and join back to one side whenever it's safe to do so

Level 1

Level 2

Level 3

Level 4

Level 5

Maybe the most difficult part of the Co-op run.

at the end level, it's fast to have players on each side

Level 6

Player 1 get's the super bomb arrow for the final boss while Player 2 stays on the right. for the [?] item, it's good to scroll up a bit before taking it so the gate's bouncing bomb are killed. While the Player 1 is getting the super bomb arrow, the Player 2 can wait behind the trees. Both player merge after the first gate and stays on the right side
