Buy it! If you like TF2, Global Agenda, Tower Defense, DoTA/LoL, etc.. you will love this game. Very funny and silly, but great action and fun. 6 Classes mixed up more like Global Agenda than TF2 but still distinct from either.

Each game is reset, to level 0 basically but there is leveling but doesn't do anything, you can unlock Custom Class slots with persistant cash for that (and titles for vanity) to mix endorsements, which are attribute boosts basically.

You earn money and juice (like Boost in Global Agenda kinda) from kills and pick ups. Theres other pick ups also. You buy upgrades with money which increases effectiveness of your stats and level of abilities which makes them better and recharge faster.

You also use money to buy turrets and upgrade them to defend your base, or activate traps or enable a jump pad or something (jump pads work for both teams and only need to be bought once by anyone for all to use, even enemies in your base.) You can also buy a wave of bots.
