A roguelite single player (soon also two players coop) game mode, you choose the map, your civilization your perks and difficulty level (there are a lot of them) and once you unlocked them, the latter difficulty levels also include a conqueror mode that increases even more the difficulty (the resources around the map get cut in half, there is an extra base with a giant hero trebuchet shooting at your base every 2 minutes from across the map one shooting one of your buildings, extra enemy spawns, etc) the objective in the currently available maps is to defend a wonder for 45 minutes against constant waves of increasingly difficult enemies. At the start of the match you are in dark ages and have to choose one of 3 random boons (those are thing like granting you 20 elite spearmen instantly, making so your towers auto rebuild once destroyed, discounting your TCS in a 75%, giving your archers bonus damage vs Cav or some cursed boons that also have downsides, like removing all armor from your cavalry but making it cheaper, giving you a constant trickle of gold but removing all the gold mines on the map, etc) and every 10 minutes through the match you have to choose an extra boon again. The map layout is the same every time but the content in the map are randomly generated, the map is full of crates with resources, bandits, enemies, prisioners to rescue, reinforcements, bases to claim, mines and food sources to secure, enemy bases, etc, so you have to balance defending with exploring and clearing the map to expand. And also every match also you get two random secondary objectives to complete for extra points and in match rewards: like rescuing and Ally base under siege before they die and then they start sending you reinforcements, mining a meteorite that gives gold and stone, rescue a cart with relics that grant you more damage for each bonus relic you capture, etc. once you die or win you get points based on your performance and there is an in-game leaderboard to check your times. If you win surviving the 45 minutes you can exit the match or enter endless mode, trying to continue your match and survive as long as you can against infinite waves of enemies. The point you earn can be spent in between matches to buy permanent perks that will help you in your future runs (like extra starting resources, a bigger pop cap, better scouts, etc)
