question about Dogyuun firepower (Toaplan collection on Steam)

[greg]

So how do I increase the firepower in Dogyuun? The attract mode shows the ship firing 4 purple lasers, not 2. I try pushing the button faster, but that doesn't work. What am I doing wrong? And there is another button that makes something appear behind the ship. I don't know what that does.

Connect to player 2 ship

Oh. So the only way to increase firepower is for 2 players to play? Is that what that force field or whatever that appears at the back of plane does?

[Steven]

Yes, using the Prisoner Beam to pick up player 2 is the only way to become stronger, as the game lacks weapon levels.
