Eight heroes drop onto one map. Hunt monsters for levels, take items from the camps and from everyone you knock out, and stay inside the circle while the ink storm closes it.
There are twelve heroes to pick from, each with its own attack and three abilities: a Ranger with arrow rain, a Knight who charges, a Mage with a meteor, a Rogue, a Cleric, a Berserker, an Engineer with turrets, a Druid who turns into a bear, a Necromancer, an Ink Witch, a Frost Warden who chains enemies in and freezes them, and a Tempest whose lightning jumps from enemy to enemy.
Two maps: a green meadow, and the Ashlands, dark ground with lava that burns whoever stands in it. The view leans back like a real arena; you can switch to straight down.
Two modes. Fast is about five minutes. Classic is a bigger map with a river you cross on bridges and a walled dungeon, where a Warden and its shades guard rare items, and the storm takes its time.
A knock-out costs you a few levels and most of your items, and you are back a few seconds later, until the last two circles. Knocking out someone above your level pays a bounty, so a good fight brings you back into it. A few times a match everybody picks one of three power-ups, with one reroll per card.
