I experienced the timeout X for the first time yesterday night, and it happened constantly. I always thought this was because of peoples poor internet connections - until it happened to me - and I have fiber. I also, for the first time ever with my PS3, had a hard freeze. I had to flip the switch on the back of the PS3 to get it to turn back on. That was rather scary. I am still finding the game loading screen times to be very long. Now though I just join a game, and then go get drinks, a snack, and then browse the internet until I finally join the game.
I expected SOCOM to be more of a tactical shooter where team work was necessary, but it turns out the lone run n'gun with the F90 or HK36, and light armour, will get you to the top of the scoreboard every round.
