I Wanna Test The Game Secret Boss Zenithega

A 2026 content drop added a secret boss to I Wanna Test The Game: Zenithega. Community showcases (including Yakku’s Version 9405 gameplay) document the unlock loop. Treat this as beta content—phases can feel unfinished or RNG-heavy until Project I Wanna tunes them.

Unlock checklist (confirmed community route)

1. Clear the normal route through Stages 1–5 and defeat Sagat.
2. Collect 10,000 Souls from that clear (Souls are the post-Sagat currency used for this unlock).
3. Return to a shop and buy Third Eye for 10,000 Souls.
4. Equip Third Eye in your item slot (PC: use shop-item toggle—X twice to equip/unequip items).
5. Activate Third Eye (X twice when equipped as needed), then re-enter the Sagat arena to trigger Zenithega instead of (or beyond) the normal fight flow.

If the arena does nothing, confirm Third Eye is equipped and activated, you have a fresh save, and your client includes the secret-boss update (see Updates).

Roblox: I Wanna Test The Game — Secret Boss Gameplay (Zenithega)

Souls economy after Sagat

Souls are not Robux. They arrive as part of the post-Sagat reward loop on the same clear that proves you can handle the main boss. Community routes treat 10,000 Souls as the full Third Eye price—there is no verified discount path. If your balance reads short, you likely need another Sagat cycle or you spent Souls elsewhere in the shop first.

Before committing all 10,000 Souls, decide whether you want the optional fight now or later. Gun upgrades from Gun Upgrades often shorten every future attempt; Third Eye only opens Zenithega. Many players finish Sagat, upgrade the gun once, then buy Third Eye when parry timing is stable.

What Zenithega is

Zenithega is a high-difficulty secret encounter with multi-phase patterns. Public notes compare the sprite style to Touhou’s Satori Komeiji—flavor only; the fight is pure Roblox rage platforming plus combat reads. Early community takes (Version ~9405) called Phase 2 extremely harsh and possibly under-tuned. Later recordings (Version ~9636) show a full clear is possible after patches—always re-check Updates.

Expect the arena to feel different once Third Eye is active: extra visual noise, orb-like hazards, or camera shifts are commonly reported. Those effects are part of why testers treat Zenithega as experimental content for I Wanna Be The Bloxxer direction—not a polished final raid.

Mid-article video — unlock + Phase attempts

The embedded showcase walks obtaining Third Eye, then Phase 1 and Phase 2 attempts. Pause at the shop purchase, copy the equip steps, then fight with a save behind you.

Fight prep (before you spend Souls)

• Gun levels still matter for DPS windows—see Gun Upgrades.
• Timed parries remain mandatory; crouch spam is still a trap.
• Expect shield / force-field style beats and projectile pressure similar to advanced Sagat reads.
• If Third Eye causes wild side effects (orbs, inverted feel, weird camera), treat them as part of the beta test and note them for Discord (Links).

Save immediately before spending Souls. If Third Eye fails to trigger, you can retry without losing the entire Sagat run—see How to Save for station placement tips near the arena route.

Troubleshooting the unlock

Symptom	Likely cause	Fix
Shop lacks Third Eye	Sagat not cleared or outdated client	Beat Sagat; rejoin experience
Purchase succeeds but arena unchanged	Item not equipped or not activated	X twice to equip, X twice again to activate
Normal Sagat fight instead of secret	Third Eye inactive on entry	Activate before stepping into arena
Instant death on spawn	Low HP or missing gun prep	Shop gun levels; fresh save

When in doubt, walk the full checklist on the Third Eye guide before blaming RNG.

Version notes (9405 vs 9636)

Showcases tagged around Version 9405 focus on the unlock proof and brutal early Phase 2. Clears tagged closer to Version 9636 suggest later tuning made the full fight more readable. Your Roblox client version may not display those labels—compare your attempt to recent videos on How to Beat Zenithega instead of assuming you are bad at the game.

After you unlock

Add the secret fight to your stage checklist. For a clear-focused companion, open How to Beat Zenithega. Normal Sagat routing stays in How to Beat Sagat and the Full Walkthrough.

Honest difficulty note

This page does not promise an easy cheese. Secret content in a rage beta is often published for testers first. If Phase 2 feels impossible on your build, document the version, watch the defeat guide after patches, and avoid random scripts that claim instant clears.
