Nebulus 2 LEVEL CODES: 05: ICEHOUSE 09: LANDANDLOVE 13: GREENTREES CHEAT MODE: Like the first game type 'HELLOIAMJMP' very slowly on the title screen so that you can skip through the levels by pressing the function keys. If you're having trouble collecting enough weaponns try typing 'HOUSEBLUES' on the up towers and 'BLUEHOUSE' on the down towers.
