I've played 3300 hours over 12-13 years. It's a free capture the flag web game that is typically 4v4 and around 4-10 minutes per match (6 min with a slaughter rule of 3 caps and an OT for ties).

There are 3 types of power ups: tag pro, juke juice, and rolling bomb. There are a few special tiles: boosts, bombs, spikes, gate switches, gravity well, and speed. There's a lot of maps that rotate every month by committee vote.

It's a good ratio of team tactics and individual skill that keeps bringing me back. The community is solid and they just slowly keep improving the experience. The community isn't huge so there's more popular regional times to have matches.

Maybe a Lemmy hug will get an infusion of new players :) Come check it out!
