I'm not sure if you checked the project convo, but I was hoping to add in some 'rune' based easter eggs based on the lot of you. These runes would be hidden, or have 'challenges' required to summon a special unit for the remainder of the level.
For example, you could name your rune and the unit summoned by it, determine their stats, kit and what you want their model to look like.
If you want one of your own, leave a message in the project convo detailing what you want for yours.
