SpeedRound is a relatively fast game that normally takes about ten minutes. It is loosely based on the RM Minuteman War. You hunt each other in a large field and you get units for killing your opponent's units.
The key to the game is that your units will die over time; you need to dynamically use your recruiter to place fresh, fully healed units near your opponent's older units to win individual battles.
You lose when all of your troops (not including your recruiter) are killed.
