Winback and Metal Gear Solid questions.

Any store that sells used games like EB or GameStop should have them all. Your questions: Cigs lower you health very slowly but two two useful things: they reveal laser traps and also have the same function as Pentazemin when using the sniper rifle to stabilize your aim. Dog tags are necessary for unlocking the Bandana and the Stealth Camo. Grip level can go to level 3 after 300 pull-ups (L2 + R2 while hanging).

Thanks man!
What does the stealth chip do? Also Is it true with 120 tags in the plant and 70 in the tanker you can get the ninja suit?

I was just wondering I have the SP. Wig and it gives unlimited ammo, so I decided to put myself in a walled in area and keep shooting (this took about 20 munites)and eventully I the back ups stopped comming, and they havent been comming since, but I havent played since then, when I turn it back on can I expect to see these guys again or did I just make things alot easier on myself?

Stealth Suit makes you completely invisible and is worn just like the BDU, meaning it unequips if you bump into someone but you can punch the hell out of people and they will be so confused by it. Pretty entertaining.

By the way, rooms refresh after you travel a certain distance away in certain areas whereas other areas do not refresh enemies.

Another note: Wigs give Raiden his infinite ammo and infinite oxygen skills while Snake keeps the classic Bandana.
