Myriad Mayhem is a challenging top down horde survival game with Roguelite and Base-Building mechanics.
Your faction’s last castle is under siege, and you are their last hope of defending it. Win the game by eliminating the enemy - or lose if they destroy your castle first.
The enemy has encampments all over the map. When you clear a region of enemies, you are free to build there. Not only do you have warfare structures like towers and barracks at your disposal, but also economy and utility structures, such as farms, marketplace and a teleporter.
If you're lucky you will find new equipment on your runs, that are then unlocked permanently.
For each run, you can choose which of your unlocked equipment you want to use and also strengthen your character or enhance your abilities through their own talent-trees. You can only have a few abilities at your disposal, so which equipment and ability combinations will you take?
When you rank up your character, you will gain gold to spend in the progression-shop in the main menu to buy upgrades that will last throughout all runs.
This game uses AI to help with localization (translations) from English to most other languages, in its current version.
