Steam is running the “Summer Camp” event, which is a massive discount on gamepacks and single games. There is also a daily challenges, among this challenge every day one is free, doesn’t require any purchase and since among the prizes there is the game Alien Breed 2 Assault.. we can say that game is free until the 10th July 2011. Basically the first day you join the summercamp group, the second day you join facebook and the third day you write a comment on a friend profile et voila Alien Breed 2 is yours if you decide so. The task can be achieved any time so you can achieve the task of the 30th June, today and so on, hope this info is useful for you.. Cya.
p.s If you don’t like some of the task, for example you don’t like facebook, you can just wait for another day, with the thing running for 10 days getting 3 tickets is extremely easy.
NOTE:Dunno through if with 4 tickets or more you can choose from better prizes.. i think i will wait to see b4 deciding.
