This effect is first witnessed at the beginning of E1L1.MAP
when Duke's vehicle goes down in flames and then explodes. The next (and last) time it is seen is at the beginning of E3L5.MAP
, when Duke's helicopter crashes and burns. It is extremely easy to do, and looks very cool.
Place either the DUKECAR
(#2491) or the HELECOPT
(#1346) and move it to the exact location and height at which you want
it to start. Its angle determines its falling trajectory. You have to
give it enough space to move, otherwise it will hit a wall and slide
down until it detonates (which looks very unrealistic). When the game
begins, the vehicle will travel forward and slowly lose altitude until
it automatically explodes.
