Killzone Mercenary (PSVita) Walkthrough, Secrets & Cheat Codes

1Game Basics

2Core Gameplay

Killzone Mercenary is a shooter that lives or dies on its moment-to-moment feel. Enemies pressure you, cover matters, and the PSVita version delivers the controls and pacing the series is known for. Success in Killzone Mercenary is about resource discipline: ammo, health and positioning. On the PSVita the combat is crunchy and readable, and the difficulty scales fairly once you stop panicking and start planning. Success in Killzone Mercenary is about resource discipline: ammo, health and positioning. On the PSVita the combat is crunchy and readable, and the difficulty scales fairly once you stop panicking and start planning. What keeps Killzone Mercenary fun is variety — weapons, encounters and set-pieces change often enough that you never settle into autopilot. The PSVita release is the one we point new players toward.

The single most important habit in Killzone Mercenary is consistency — the systems reward players who learn the core loop before chasing shortcuts, and almost every wall you hit is a sign to practice one mechanic, not to abandon the run.

Priority checklist (do these first):

• Upgrade mobility early so you can escape bad engagements.
• Prioritize the heaviest enemy first to reduce incoming damage.
• Manage ammo; melee or sidearm when low rather than reloading in the open.
• Keep moving — a stationary target is an easy target.
• Learn grenade arcs for the two chokepoints you fight most.

Common beginner mistake: The error that gets you killed in Killzone Mercenary is reloading in the open; the reload animation is your most vulnerable window.

3Step-by-Step Walkthrough

Follow this order and you will clear Killzone Mercenary on PSVita without grinding for hours. Each step builds on the last, so do not skip ahead — the early habits make the late game trivial.

1. Upgrade mobility early so you can escape bad engagements.
2. Prioritize the heaviest enemy first to reduce incoming damage.
3. Manage ammo; melee or sidearm when low rather than reloading in the open.
4. Keep moving — a stationary target is an easy target.
5. Learn grenade arcs for the two chokepoints you fight most.
6. Save special weapons for vehicle or boss phases.
7. Use cover between bursts; peek, shoot, retreat, repeat.
8. Replay a mission on easy to learn spawn patterns, then step up.
9. Finish on the hardest setting only after you know every encounter.

Once the campaign is done, replay on a harder setting or chase 100% completion; the systems you learned on the first run make the second feel completely different, and most Killzone Mercenary players agree the post-game is where the real depth lives.
