Hexmental

The elements are alive!
Six elements and an island that reacts to all of them. Freeze the lake and walk your squad across it. Put lightning in the pond they're standing in. Rain on their fire and vanish into the steam. Fire, Water, Lightning, Ice, Nature and Rock mix, cancel and set each other up. Come and find out what you're capable of.
Same turn. Same time. Nobody waits.
Both teams plan the same turn at once. Move, cast, or sit tight and bait them, whatever the turn calls for. Then it all plays out together. Their wave rolls through the hex you just left. Your bolt lands in the puddle they were about to step into. Nobody gets to react. Better read wins.
Build as you go and hunt the crown
One player on each team wears the crown. Choose your spells round by round and eliminate their king. Do it three times and the game is yours. Crown changes heads every round, so everyone gets their turn being hunted.
A new island for every game
Generated fresh, hidden in the fog, yours to scout. Whatever you do to it stays done: the wall you raised in round one is still standing in round four. Freeze it, flood it, torch it, spawn a bush and hide in it. Be creative and be fast; the sea is rising  
Solo. Co-op. Online.
Run the tournament alone or with a friend: an endless gauntlet of AI teams, every one of them pushing the elements somewhere you haven't been yet. Or take it online, two or three to a side, both teams planning at once and showing how they like to bend the elements.
Short matches and every turn matters
No APM. No grinding sessions. No sitting through someone else's twenty-minute think. Plan, reveal, regret or rejoice, go again. Think you can read them? Prove it.
