This game is a hack of "Major Havoc".


Changes include :
* 2 new Warp codes and Warp bonus points change.
* 4 new levels.
* Added speech support.
* Game a bit easier.


* Warp Codes : It's possible to warp to higher levels in Major Havoc from the start of the game by using certain codes. This is useful to not only be able to get through the game more quickly, but each warp also gives a fairly hefty bonus for carrying it out. This is done by playing the mini-Breakout game at the bottom right-hand corner of the screen when the game starts. The game will have a phrase such as, 'Enter Red Warp 00' at the bottom of the screen. What you do is use the controls to 'dial in' the first digit of the appropriate code given below, then press fire to serve the ball and repeat as necessary. The codes are :
Red code - 23, 250,000 pts, Level 4.
Yellow code - 46, 550,000 pts, Level 9.
Green code - 824, 650,000 pts, Level 10.
Aqua code - 315, 850,000 pts, Level : 13.
Purple code - 683, ?, Level ?.
Rainbow code - 948, ?, Level ?.

Note that you can only enter the codes in the order they're given - it's not possible to enter, say, the red warp code followed directly by the Rainbow warp code.
