It's like Halo, but free to play and kinda generic. The Portal system tho, is amazing, you can do millions of strategys using portals, and the game teaches you pretty well at the tutorial. I recommend, its free to play, but I wouldn't spend any money on this, because it's too generic, all the characters are too random, nothing memorable. The game modes are really fun, so yeah, I think you should play if you like halo and want something new, but you shouldn't spend money on this.
