Ok guys, have you played this game called Shellfire ?
It takes heroes from MOBA and made it into a First Person Shooter. Every character has a unique abillity from stealth, to extra firepower and many more. This is one of my fav characters which has fast attack and grenades.
It also has a powerup which can obliterate a lot of people within seconds as you can see, i got a killing spree once more powerup came up !
Great game to have, go download it SHELLFIRE ! Available on Google Playstore and its Free to Play !
