L4D2 free, and disappointing

[Elandyll]

L4D2 was free for a little while on Christmas day on Steam.
I took advantage of the offer, and finally gave it a try today.

Disclaimer: I do not play FPS in multiplayer. I have no interest in this kind of things other than the occasional adrenaline rush for very short periods of time.

So, I figured at least there's the single player, which I somewhat enjoyed in L4D1 for a little while.

Man, I'm not sure if TLOU spoiled me on survival/ shooting (TPS for TLOU)/ zombie apocalypse games, but my first 10 minutes have been complete garbage. Still no story (more or less expected after L4D1), but the gameplay has not changed at all either. Except that the game seems to throw even more zombies at you in waves of drooling running morons (er, zombies), and, well... that's it.

For now, I just don't get it, unless the praises the game got back in the days were solely for MP...

Will try again sometime, not much hope for it though.
