MGS4 Weapons and Drebin Shop Guide: Best Purchases by Act
The best weapons to buy, when the shop discounts, and a practical loadout for stealth, bosses, and alerts.
Buy utility before damage
Suppressors, tranquilizer ammunition, and reliable optics do more work than a bigger caliber. Your loadout should make your next decision safer, not louder.
- Prioritize suppressors for the Mk.2 Pistol and assault rifle.
- Keep a sniper rifle for bosses and long sightlines.
- Sell duplicates only after checking whether the next act unlocks a useful upgrade.
A flexible all-purpose loadout
Carry one silent sidearm, one accurate rifle, one long-range option, and a non-lethal answer. This covers patrols, armor, and scripted arena fights without overfilling your inventory.
Drebin discounts
Discount windows can change the value of hoarding weapons. Check the shop before a major purchase and spend excess points on ammo you will actually use.
