Metal Gear Solid need help!

[sergiodaly]

if you are stuck at the boss battle... you can search the web for a solution. after the battle you don't need any card to progress because the dieing mantis opens the door for you... if that didn't happen the game did glitch on you i guess... tell us more details about the issue.

edit: just remember, that the colonel did say not to use any guns on Meryl so is normal that you cant use R2 or L2... just knock her out by pushing square near her...
