Basically, my idea is when you complete the game, maybe after a certain amount of stars or after all elite stages, you unlock game modifiers
the way it works is you just access a menu, and you activate the modifiers. Theyre kinda similar to say.....i don't know, maybe Destiny level modifiers.
They're there to basically have some fun and give more play time and maybe experiment a little bit.
Multiple modifiers can be active at the same time, so you can make some hilarious stuff, but you can't gain stars, gems, or achievements if any of them are active (to prevent exploits).
some modifiers can favor you, some favors the enemy, some give effects to both.
Example of Modifiers :
Brawler : Melee damage set to 250%
High Explosives : Explosion damage set to 250%, explosive AoE set to 250%
Fresh Recruits : Barracks train +2 soldiers, Reinforcements have +1 soldier in them.
Martyr : If your hero dies, lose 2 lives.
Indiscriminate justice : any kind of explosion can damage both friendlies and enemies.
Let me know what you think of this stoopid idea :p
