Metal Gear Solid 4 Beginner's Guide: 15 Things to Know Before Act 1
A clean first-run setup covering camouflage, alerts, Drebin, weapons, healing, and the habits that make MGS4 easier to read.
Build a stealth-first loadout
Keep the Mk.2 Pistol, Solid Eye, and a non-lethal option ready. Your first goal is information, not damage: scan patrols, mark threats, then choose a route.
- Use the Mk.2 Pistol to disable cameras and isolate guards.
- Switch the Solid Eye to night vision only when it solves a visibility problem.
- Keep one recovery item available before every scripted encounter.
Understand the alert economy
An alert is not automatically a failed run. Break line of sight, move away from the last-known position, and let the search cool down before crossing the same lane again.
- Crawl through grass and shadow instead of sprinting between cover.
- Hide bodies away from patrol intersections.
- Save tranquilizer ammo for officers and scouts who can restart a search.
Spend Drebin Points deliberately
Drebin's inventory changes through the story. Buy suppressors and upgrades that remove friction from every mission before chasing novelty weapons.
