Pacifism mode in SB2 was originally very predictable and boring, and the very best strategy was to just fly around in circles hoping that not too many enemies would spawn in your way.That is no more.
The asteroid spawn rate is now twice as fast, and will spawn anywhere outside the grid and make its way toward the center, then back out to the opposite side.
This effectively makes the higher scores easier to achieve, while keeping players on their toes. Click to Play
Click "pacifism" in the game modes section of the menu, then click "go" or press space.
Other modes may be reworked depending on what may be needed.
Also, BOSSES mode has its own theme! Give it a listen
