To finish any scenario in the campaign game, hold X + P + C (in that order) and press Left. A menu will appear allowing the choice of achieving a major victory, minor victory, loss, or quitting the game.
A bug in the 3DO version prevents the game from progressing to Washington when a major victory is achieved in Sealion 43. However, the game will allow access to Washington through Sealion 40.
Saved Game bug
A save game can only exist with three other game saves (you can only have three other games saved in order to save one game of Panzer General). SSI has announced no plans to fix this, and contends that because the save game will become very large as the game progresses, there will be no room for any other games.
Game Shark Codes
There is a bug in the game that allows you to place your
purchased units any where on the board. All you have to
do is after you select your unit and hit the Buy button
is before you place the unit, hit the save key. This will
allow you to place the unit anywhere your units can see.
