Rapid assault came out for 386 and 486 in 1995. You choose a vehicle and have to complete missions fighting crime and then find the flag to the next level. I played on os2 warp, but there is a dos 6.0 version too. The graphics are of course outdated now but were nice for the time. The game is quite fun to play. I remember being in awe for this game where you could choose from several hovercrafts I believe they were, each having advantages and disadvantages. One is fast but lacks armor, one has lots of armor but is slow and other options. I would choose the fast one and then just race the streets and shoot anything that moves.
