BumFight!

A no-frills QBasic turn-based top-down combat simulator with an unusual and
controversial theme: bumfights, or otherwise put, combat between the homeless!
Their arena is the mean streets, and trashcans become the dispensers of
various bonuses (feeble improvised weapons and armour) and penalties (health
deductions from vicious rats! eek!) Game settings allow for play between two
to eight human or computer players, with the final winner heading to the high
score chart with a money count totaling change the player found in the garbage
and retrieved from the bodies of defeated opponents.
