| should continue the above given methods and soon he'll be finished. |

Complete the Raven boss fight in Metal Gear Solid, get the Level 7 Keycard, and navigate the treacherous warehouse and gun camera room.

Alright, you've just finished up that tough fight with Raven! He's going to spill some important story details before he kicks the bucket, and as a parting gift, he'll hand over the Level 7 Keycard. Honestly, it's nice to see him do one useful thing!

Once all those cutscenes and dialogue wrap up, you'll have that Level 7 card. This means you can now access pretty much anywhere. Head for that big door at the north end of the warehouse and go through it. You'll emerge into a new section.

As soon as you enter, equip your Thermal Goggles. You'll spot two trap doors right in front of you on the floor – be careful not to fall in! Before you move on, grab the Chaff Grenade sitting to your left. Keep pushing forward a bit more. You'll soon reach an open area, and you'll notice it's absolutely crawling with gun cameras. Seriously, hundreds of them!

Quick! Throw that Chaff Grenade you just picked up. While they're all confused, make a dash for the door located in the far corner of the room. If you're feeling brave and want some extra missiles, you can go to the right of that door where there are stairs, but otherwise, just make a run for the exit.
