They icons an graphics are outstanding, the mods are very friendly. If you actually try to play the game you will find unlocking new characters is rather easy.
The owners are adding new characters all the time.So it never gets boring. You will always have a new character to try an meet to get him.
This game also has events such as Protect The Base (PTB),Boss Battle,Dual Boss Battle,Warzone,Death Match. An its not just about kills to unlock characters. Its about other things (witch im not allowed to tell).
So if you want a fun game to spend your time on
Check out Megaman Wars.
This is just my characters list an im missing a few as you can see.
This is a event called "protect the base"
