System of achievements

Unknown

Hi. Sorry for my english.
I would like to propose a system of achievements for each character.
For example:
During one round destroy more 5 tiles 1 times, 2 times, 5 times, etc.
During one round made 1 critical hit; 2 critical hit, etc.
Defeat Spider-Man Venom or Doctor Octopus 1 times; 2 times, etc. Each character can put his opponent.
Win one round; 5 rounds; 10 rounds, etc.
Defeat team Doombots, H.A.M.M.E.R. 1 times; 5 time, etc
Get the first (10, 50) in PvE, PvP, season, etc.
Achievements complicate and give them by appropriate rewards: ISO, HP, covers, etc.
Achievement can be obtained for each character once. If the player starts a new, it is possible to obtain re-achieve.
