I was looking through my
PC gamer mag the other day and found a small article about this game called Karboom
Looked on their website and looked pretty good so I made and account.
At the moment if you make an account it gets upgraded to premium free of charge, its the first 500 accounts and theres like 82 left
http://karboom.net/
its like sumo wrestling in cars but with about 6 'mutations' which are like special rules
theres one called tag where 1 person is on it and they ram the next person to pass it on
but if your 'it' then your score doesn't go up
So far seems to be a pretty good game no one hosts any games as far as I can see
but it is only at version 0.2.2 or something
