After the initial cinematic, you'll find yourself in a jungle environment. Follow Spider, who will guide you through the initial path. This segment introduces you to basic movement and environmental traversal. You'll encounter your first few Omega Force soldiers. Spider will demonstrate a stealth takedown. Mimic his actions by crouching (C) and approaching an enemy from behind, then pressing the melee button (F) for a silent kill. Continue following Spider, using cover to avoid detection. He'll point out various environmental hazards and opportunities.
As you progress, you'll come across a small patrol. Use the tall grass for cover and practice your stealth takedowns. Remember, headshots are instant kills for most basic enemies. If you get detected, be prepared for a firefight. Your starting weapon, the Fazertron, is a reliable assault rifle. Keep an eye on your mini-map for enemy positions. Eventually, you'll reach a vantage point overlooking the Omega Force base, triggering the next objective.
