I got another etqw mod in my mind. How about instead of the GDF vs Strogg, it is the Boston Celtics vs New York Knicks?
Objective 1 = posess the orange ball
Objective 2 = put orange ball inside orange hoop with net
Objective 3 = repeat and do it more times than other team
Time limit = 12 min, time resets 3 times back to 12 min after time expires.
