Post-Game Content

Congratulations, Syndicate Agent! You've navigated the labyrinthine conspiracies, faced down the Syndicate's deadliest operatives, and brought down Muro. But the world of Oni doesn't end with the final cutscene. For the dedicated agent, there's a wealth of challenges, secrets, and opportunities to hone your skills even further. This section details the comprehensive post-game experience, guiding you through every last collectible and combat scenario.

Replaying Missions for Rank and Secrets

The most immediate and rewarding post-game activity is revisiting previous missions. Each mission has hidden items and opportunities to achieve higher ranks. Aiming for an "S" rank on every mission is the ultimate test of your combat prowess and environmental awareness.

Hidden Item Checklist

• Data Disks: These are often cleverly concealed, requiring keen observation or specific environmental interactions to uncover.
  • Mission 01: Training: Look for a Data Disk near the firing range's elevated platform.
  • Mission 03: The Syndicate Warehouse: One Data Disk is hidden behind a stack of crates in the main storage area, accessible after clearing the initial wave of enemies.
  • Mission 07: Vandal's Sanctuary: A particularly tricky Data Disk is located on a high ledge in the central chamber, requiring precise platforming or a well-timed jump from a higher point.
• Weapon Blueprints: Collecting these unlocks new weapon variants or modifications for use in subsequent playthroughs or specific challenge modes.
  • Mission 05: The Atmospheric Processor: A Blueprint for the "Mercury Bow" can be found in a ventilation shaft near the central cooling unit. You'll need to destroy a weak grate to access it.
  • Mission 10: Konoko's Apartment: The "Plasma Rifle Mk. II" Blueprint is hidden in a secret compartment behind a bookshelf in Konoko's living quarters. Interact with the bookshelf to reveal it.
• Health Power-ups: While not always "hidden" in the traditional sense, some health power-ups are off the beaten path and can significantly impact your mission score.
  • Mission 02: The TCTF Headquarters: A large Health Pack is tucked away in a rarely visited office on the second floor, accessible by jumping over a partition.

Achieving "S" Rank

To achieve the coveted "S" rank, you'll need to master several aspects of gameplay:

1. Combat Efficiency: Minimize damage taken, maximize headshots, and use environmental hazards to your advantage. Focus on chaining combos and disarming opponents.
2. Speed Runs: Complete missions as quickly as possible. Learn enemy patrol routes and optimal paths through each level.
3. Collectibles: Find every single hidden item within the mission.
4. Enemy Takedowns: Defeat all enemies in the mission. Leaving even one alive can impact your score.

Challenge Modes and Unlocks

Beyond replaying missions, Oni offers dedicated challenge modes that test specific skill sets.

Time Attack Mode

Unlocked after completing the main story, Time Attack mode challenges you to complete each mission under a strict time limit. This mode is excellent for practicing speedrunning techniques and memorizing level layouts.

• Strategy: Prioritize movement and combat efficiency. Use the "Hyper-Jump" ability frequently to traverse large distances. Don't engage every enemy; sometimes, bypassing them is the faster option.
• Rewards: Achieving gold medals in all Time Attack missions can unlock exclusive character skins, such as the "Syndicate Elite" uniform for Konoko, offering a cosmetic change for future playthroughs.

Survival Arena

Accessible from the main menu after completing the game, the Survival Arena pits Konoko against endless waves of increasingly difficult enemies. Your goal is to survive as long as possible and achieve the highest score.

• Location: Select "Survival Arena" from the main menu. You'll have access to several arena layouts, including "The Pit," "Rooftop Rumble," and "Industrial Complex."
• Enemy Waves: Waves will escalate from basic Syndicate Thugs to heavily armored Strikers and even Elite Guards. Later waves introduce multiple enemies with energy weapons and powerful melee attacks.
• Strategies:
  • Weapon Management: Conserve powerful ammunition for later waves. Prioritize picking up new weapons from fallen enemies. The "Screaming Eagle" pistol is excellent for headshots, while the "Wave Motion Gun" is devastating against groups.
  • Environmental Awareness: use cover, choke points, and explosive barrels to your advantage. In "Industrial Complex," the moving platforms can be used to separate enemies.
  • Melee Mastery: Don't underestimate Konoko's hand-to-hand combat. Disarming enemies and using their own weapons against them is crucial for conserving your own ammo. Practice the "Dragon Punch" and "Spin Kick" combos for maximum crowd control.
  • Health Pickups: Health pickups are scarce. Only grab them when absolutely necessary, or when you're about to take significant damage.
• Rewards: High scores in the Survival Arena can unlock concept art galleries, developer commentary tracks, and even a "Big Head Mode" cheat for the main campaign.

New Game+

Upon completing the game, you'll unlock New Game+. This mode allows you to restart the campaign with certain advantages carried over from your previous playthrough.

• Carried Over:
  • All unlocked weapon blueprints.
  • Any collected Data Disks (though you can still collect them again for score).
  • Character skins unlocked through challenge modes.
• New Challenges: New Game+ often features increased enemy difficulty, with more aggressive AI, higher health pools for enemies, and more frequent appearances of elite enemy types from earlier missions.
• Ultimate Goal: Completing New Game+ on the highest difficulty setting (e.g., "Hardcore" or "Nightmare") is the ultimate challenge for any Oni player, proving your mastery over every aspect of the game.

By engaging with these post-game activities, you'll not only extend your enjoyment of Oni but also gain a deeper appreciation for its intricate combat system and level design. Good luck, agent!
