Chapter 1 - Walk-through
This section provides a complete walk-through of Metal Gear Solid 4. There are many ways to play Metal Gear Solid 4. You can complete the game as a one-man killing machine with little concern for alerts and ammunition expenditure, or you can choose a stealthier route and attempt to finish the game without kills or alerts. Furthermore, many situations feature multiple solutions encouraging experimentation. Weíll provide tips for a variety of gameplay styles and include plentiful tips on finding optional items, completing secondary tasks, and defeating specific enemies and bosses.
Crawl under the truck in front of you and grab the ration. Keep moving to the right and duck and crawl under the other truck to trigger the cut scene. Pick up the AK-102 off of the ground. Move to the left or right around the building to trigger the next sequence and the arrival of the Gekkos. Avoid the Gekkos—there's no need to fight.
As you follow the instructions to proceed north, you can search some buildings to find additional rations and ammo. For example, on the southern side there's a two-story building; search the upstairs for a ration and ammo. On the southern side of this building there's debris but you can crawl under for a ration.
Move around this building on its northern side. Search another destroyed building on the right side of the street for ammo and a ration inside. Continue following the objective north until you trigger another cut scene.
Act 1 - Liquid Sun
Middle East: Red Zone
Turn around and search the alley behind you for a ration and some ammo. Continue the other way and start to cross the street, noting the soldiers on the right, to trigger a cut scene.
Search the shadow across the street for a petro bomb. Check the rooms across the street for another ration. You can also maneuver into a crawlspace that contains a compress. Another building across the street has another petrol bomb, a locker with noodles, and a cardboard box on the shelves by the locker.
The bulk of the guards are near the intersection. Stick on the right side of the road. Use the destroyed car for cover and enter the building on the right to find more items—ammo, ration, compress—and use the crawlspace here to move through.
Stay in the crawlspace until any soldiers ahead move away. Stick in the shadows on the right side. Reach a locker room with ammunition; search the locker for a regain. Avoid any guards patrolling this area. The opposite side of this area contains a ration, ammo, and compress if you want to search it. Cross the street toward the right side and into the checkpoint.
Explore the area around the staircase for items, such as a compress underneath the stairs. You can cross through the area's middle section. The building's provide decent cover and anytime you are spotted you can crawl back inside and activate OctoCamo. Locate a staircase inside one of the first buildings and traverse the top floors. Upstairs youíll find ammo and continue further to grab a Playboy as well as a couple noodles.
Ascend the staircase near the start. This will take you around many of the ground patrols if youíre hoping to remain out of sight. Roll as instructed over the small gap. Knock out the guard ahead. There are stairs back down here; search lockers down there for a ration and regain. Drop down over the ledge ahead.
Drop down when the coast is clear and snag a compress in the right corner. When exiting the area, check carefully for patrols to the left. Exit and hid in an alley on the right; there's another ration there. Watch for the patrols to move past. Crawl into the next structure on the right side to trigger a cut scene. You've found the Metal Gear Mk. II. You gain a couple new items, the solid eye, an operator, and a valuable weapon for stealth players, the Mk 2 tranquilizer pistol.
Search around the corner to the left for a ration. Move out to the east side and snag some ammo by the barricades. Wait until the soldiers move away before going for the ammo. Your goal is due north—right in the middle of the firefight.
Cross behind the APC and crawl along the buildings until you reach the area behind the sandbags. Gather up any discarded ammunition, snag an RPG in the back corner (if you didnít use it to destroy the APC as described in the tip), and go down the stairs into the Militia Safe House.
