HISTORY

1941 - Counter Attack (c) 1990 Capcom.

A vertically scrolling shoot'em up. Player 1 uses a P-38 Lightning and Player 2 uses a Mosquito B Mk.IV.

- TECHNICAL -

Capcom Play System (CPS) hardware
Game ID : CP-S No. 07

Main CPU : 68000 (@ 10 Mhz)
Sound CPU : Z80 (@ 3.579545 Mhz)
Sound Chips : YM2151 (@ 3.579545 Mhz), OKI6295 (@ 7.576 Khz)

- TRIVIA -

1941 was released in February 1990 as the 7th CP-S release. It is the first Shoot'em Up to add +1 to the score when a continue is used.

Here is all the official bosses names :
* Stage 1 - Leviathan
* Stage 2 - Bismarck
* Stage 3 - V3Rocket
* Stage 4 - Krote
* Stage 5 - Leviathan
* Stage 6 - Gotha

Historical inaccuracies - V3Rocket : The real V3 was a Super Gun, not a rocket. Furthermore, 'V-weapons' would not appear until 1944.

Default high-score table :
1ST 30000 CAP
2ND 29000 COM
3RD 28000 CAP
4TH 27000 COM
5TH 26000 oO2

Pony Canyon / Scitron released a limited-edition soundtrack album for this game (Final Fight : G.S.M. Capcom 3 - PCCB-00030) on May 21, 1990.

- UPDATES -

At the 5th position on the high score table, the Japanese version says 'j01' instead of 'o02'.

- TIPS AND TRICKS -

* Hint : Your airplane doesn't lose energy when it collides with cliff-walls, buildings etc. Instead it will rotate a bit after such collisions. That means you can tumble up and down these obstacles (keep on colliding), and if you keep shooting, your shots will go in all directions. This way you can clear up a lot of enemies when you are under pressure (while rolling you are invincible).
