I am definitely buying all the DLC missions for this. (no.. seriously)
And yet..I hated the last one I played on PS2.
But honestly.. crawling around on MUDDY ps2 texture maps was just not fun.
And the PS2 one lacked many of the tools.. perks.. cheats that make you feel so bad ass.
SE4 looks great.. and the game-play makes you feel like a real Billy Badass.
Just put it on Hard at least.. since easier difficultly settings makes it so easy you don't even need to be a sniper.

And then hardcore mode it if you hate your life (no map not nothing.. it's "authentic").
