i know it is multi console but i dont have an x-box so i got it new on ps3 for....20$.yes thats right 3-5 games in one for 20$ new!!!!
i just have to say portals is amazing.also the cake is a lie. it is the best puzle game since tetris.i played that first and it really helped me out with the controls for half life two. it has a nice learning slope so you arent just thrown into the frew and dying all over the place...the same can not be said for half life 2. you have no h.u.d. and no real life meter, so ifyou get shot a couple time and hide behind a wall for a second or two you are at "full life"....which can be very usefull
