Warframe 1999 Secrets Guide: Caliber Chicks 2 Arcade, Atomicycle Liveries & Höllvania Hidden Collectibles

The 1999 update buries a surprising amount of content off the main path. An arcade game co-developed with Sumo Digital. Motorcycle customization you'd expect from a racing game. Drifter fashion that screams 90s. If you just run bounties without poking around, you're missing half of what makes this update special.

Caliber Chicks 2

Hidden in the Höllvania hub is an arcade cabinet running Caliber Chicks 2, a full side-scrolling beat-em-up. This isn't a five-minute gimmick — Digital Extremes co-developed it with Sumo Digital, the studio behind Sackboy and LittleBigPlanet 3. It's a complete game with multiple levels, a scoring system, and unlockable rewards tied to your performance.

To find it: from the bounty board, head left past the workbench toward the back wall of the subway station. There's a flickering neon sign above a tucked-away alcove. The cabinet is against the wall, an old CRT monitor setup with two joysticks. Easy to walk past if you're not looking for it.

The game itself is a love letter to 90s arcade brawlers — Streets of Rage, Final Fight, that era. You pick from two characters (the titular Caliber Chicks), each with different combos and special moves, and fight through waves of enemies across urban environments. The controls are simple: attack, jump, special. But the enemy patterns and boss fights have actual depth. I lost to the stage 3 boss three times before I figured out her attack telegraphs.

High scores unlock rewards in the main game. A certain score threshold on stage 1 gets you a unique glyph. Clearing all stages unlocks a Caliber Chicks-themed Atomicycle livery. There's also a hidden bonus stage accessed by not taking damage through the first two levels. The rewards are tracked through an in-game achievement system tied to the arcade cabinet, not the main Warframe achievement list.

The cabinet tracks local high scores. Your squadmates' scores show up if they've played on the same session. There's no online leaderboard — it's intentionally retro in that way.

Atomicycle Customization

The Atomicycle garage in Höllvania is more extensive than it first appears. Beyond the basic color and decal options you unlock from the quest, there are hidden liveries tied to specific activities.

Livery categories: body paint, decal sets, wheel designs, exhaust effects, and handlebar styles. Most are purchased with Hex standing from the syndicate vendor. But several are hidden behind achievements:

A Techrot-themed livery unlocks after defeating your first Technocyte Coda. The bike gets this organic, Infested look with pulsing veins that glow in the dark. It's unsettling and also the coolest bike skin in the game.

A Scaldra military livery unlocks after completing a certain number of Assassination runs against the H-09 Efervon Tank. Military green with armor plating visuals.

The Caliber Chicks livery from the arcade cabinet gives the bike a pixel art decal set that genuinely looks like it belongs on a 90s arcade cabinet side panel.

A seasonal livery unlocks for each season you're active during — winter gives an ice-themed design, summer a sun-bleached look, and so on. These are time-limited, so if you want the full set you need to log in at least once per season.

Exhaust effects are purely cosmetic but genuinely fun. Different exhaust flames, colored smoke trails, spark effects when you drift. The Hex standing costs are reasonable — a few days of casual bounty running gets you one effect.

Performance parts are separate from cosmetics. Engine upgrades increase top speed and acceleration. Tire upgrades affect handling and drift control. Boost upgrades increase the turbo duration. These come from bounty rewards and Hex standing, not the market. No platinum shortcuts for performance — everyone earns these the same way.

90s Drifter Customization

The 1999 update adds a batch of 90s-themed Drifter customization options to the appearance menu. These aren't tied to Höllvania content specifically — they unlock when you start the Hex quest and remain available everywhere.

New hairstyles include several period-appropriate cuts. New facial hair options. Clothing options lean into 90s fashion: leather jackets, band tees, ripped jeans, combat boots. The aesthetic is grunge-meets-cyberpunk and it actually works.

These are unlocked through the Hex quest progression, not purchased. You'll get a few options at the start, more as you progress through the story, and the full set after completing the questline.

The Drifter customization applies to the Drifter in all content, not just Höllvania. So your 90s look carries over to Duviri, relays, and anywhere else the Drifter appears.

Hidden Höllvania Details

The hub has environmental storytelling worth paying attention to. Graffiti on the walls changes as you progress through the Hex questline — some of it is the Hex members leaving messages for each other. Newspapers scattered on benches have readable front pages that reference events in the Warframe timeline filtered through a 1990s media lens.

The music playing in different hub areas comes from actual period-appropriate genres. The arcade area plays chiptune versions of Warframe themes. Near the KIM terminal, there's lo-fi beats. The garage plays rock. The audio team clearly had fun with this.

There's a radio near the bounty board that broadcasts Höllvania news updates. These change based on your quest progress and seasonal rotation. Sometimes they reference your recent mission results.

If you stand near the Hex members in the hub long enough, they have ambient dialogue with each other — not triggered conversations, just background banter. Arthur and Aoi argue about tactics. Lettie and Amir have surprisingly funny exchanges. These ambient lines cycle and there's a lot of them.

KIM Easter Eggs

The KIM messenger has hidden conversation paths that only trigger under specific conditions. Sending a message at exactly midnight in-game time during Winter season unlocks a unique dialogue with Eleanor. Using specific emoji combinations in responses can trigger joke responses from Amir. These are entirely optional and don't affect Chemistry or rewards — they're just there for people who dig deep.

The KIM interface itself has period-accurate details: the typing sounds match a mechanical keyboard from the 90s. The message notification sound is an actual ICQ "uh-oh" homage. The away messages Hex members set when offline are era-appropriate AIM-style statuses.

None of this is essential for progression. But it's the kind of detail work that makes Höllvania feel like a real place rather than a quest hub you rush through. Spend some time just exploring between missions. The update rewards curiosity in a way Warframe usually doesn't.
