- According to video reference(could only find 1), redclash player bullets should be
|
||||
4*2px red on the 1st half of the screen and 8*2px yellow on the 2nd half, zerohour
|
||||
bullets are correct though(always 8*2px magenta)
|
||||
- Sound (analog, schematics available for Zero Hour)
|
||||
- Sound (analog, schematics available for Zero Hour), redclash sound is not the same
|
||||
|
||||
BTANB:
|
||||
- redclash gameplay tempo is erratic (many slowdowns)
|
||||
- redclash beeper sound stops abruptly at the canyon parts
