Description 1) During gameplay press SHIFT and ENTER to toggle cheat mode (ship will start flashing).
2) To complete the normal bonus sequence in each wave, collect all of the B.O.N.U.S. symbols as stated in the game docs. But it also reads: "There is also a Secret Bonus per game sector, but obviously we can't tell you much about that."
Well, to access the Secret Bonus, collect the B.O.N.U.S. symbols in EXACTLY that order, without any repetition, i.e. picking up "B" first, then "O", etc.
