And a slow reply you shall receive.
I am going to rip apart your whole post, chew it and spit it out right back at you. So be prepared.
1) Does css come with a zombie/surf mod? the retail version i'm talking about here. No it does not, it's a mod that you have to download. Not part of CSS, therefore you cannot use that against INS

If people wanted to shoot zombies or do whatever it is you do in surf, they would a) make a mod for it b) head to css and play it there.
2) "Jumping in INS sucks" Really? I dare you to put on every single bit of gear a standard infantry man uses, and try to hop around like you do in CSS. Not happening.
3) Your little argument about CSS having crosshairs and INS not. Well.. duh, INS is a mod made to provide the player a sense of realism in a video game. Any crosshairs in the real battlefield?
4) I remember seeing something about CSS having millions of gametypes, I only recall hostage and bomb.
In the end, it all comes down to this. INS - Tactical Realism Mod CSS - run and gun arcade game
So hold your petty arguments and comebacks until saturday, because CSS is gonna get a whooping they have never seen before. Oh yes
