http://kotaku.com/5306691/korean-pc-game-rips+off-team-fortress-2H.A.V.E. Online is your run-of-the-mill shooter that looks like Toy Story in Man-O-War's bedroom. From the trailer I am guessing you can play as an anime girl, a bad anime girl, or a robot and equip whatever weapon you want(mostly generic futuristic bulky laser guns) regardless of your avatar. It looks like you can pick up batteries or some shit to get a buff like invincibility or something else that makes you glow. Not only does H.A.V.E. Online's trailer have A LOT of bits that are identical to TF2's trailers and Meet the Team videos, but they also threw in a few baseball bats wielded by speedy anime girls and a grenade launcher that works and fires exactly like the Demoman's.
There are a lot of swell references in the article including the side-by-side comparisons I don't want to directly embed here.
EDIT: Psyburn has narrated the intro for a trailer of it on youtube
