Gunbound revolution takes another step in jazzing up the 4 year running game. The most current and biggest update, Season2, introduces a new game mode known as Power Ball Mode, where like Supersmash bros. Brawl, obtaining a ball gives u powers that only different forces or items would have given you, such as dual or thunder. Another effort in making GB more enjoyable are secondary expendable items. You can use these new items in conjunction with the old expendible items such as dual. Some of these items include vampire - steals enemy HP, homing missle, and team power up. A bunch of new mobile balances give you a chance to actually 'like' a previous mobile which you would hate getting in random mode, such as grub, which does way more damage now. If you were tired of the old theme songs, there are now 4 more new songs that gives the game a new feeling. So if you havent been on GB in a while, or havent heard about it at all, I think its time to join the new evolution of an old skool game.
