Shop verdict

Worth it if you like Overpass’s creepy carnival vibe and you’re willing to spend five extra seconds in inspect. Skip or bargain hard if you only care about list thumbnails—this skin’s whole joke is on the other side of the gun.

Monster Trade-Up (weapon | 怪物汰换) is a Mythical finish on the XM1014 from the 2024 Overpass Collection. Valve’s pitch is simple: monster art on both flanks. The flavor line—“don’t look at the other side”—is basically a buyer’s warning. One side can look crisp in a screenshot while the mirror face is washed out or asymmetric. Treat inspect like a second quality gate, not optional fluff.

What you’re actually buying

• Drop context: Live since 2 Oct 2024, bundled with The Armory pass wave; same Overpass 2024 family as the collection line.
• Sources: 2024 Overpass Collection drops; Budapest 2025 Overpass Souvenir Package.
• Designer: Valve.
• Wear: 0.00–0.75 (Factory New through Battle-Scarred). Low float keeps ink edges sharp; high float smears outlines and muddies the palette—bad for a hand-drawn piece.
• Look: Custom illustrated style—monsters read as painted-on, not flat sticker slaps. Strong identity among souvenir-tier XM1014s if you run shotgun up close and inspect often.

Inspect & wear checklist

1. Side A: Composition intact? Claws/faces still readable?
2. Rotate: Side B—does it match quality, not just theme?
3. Wear hotspots: Scuffs that eat line art matter more than generic metal scratches.
4. Market listing: Same float on C5GAME or Steam can look totally different—compare greying and fade on both faces.

Price sanity

Mythical + dual-art gimmick + two supply paths (collection + souvenir) = prices that swing with “how clean is the pair,” not float alone. For set collectors chasing the 2024 Overpass lineup, this is a sensible XM1014 slot. For pure stat players, it’s vanity—still fun vanity if you verify both sides.

Expert muttering

I’ve passed on “good float” listings because the back looked like it lost a fight with a belt sander. The line about not peeking the other side? That’s Valve trolling impatient buyers. Slow inspect beats regret. On C5GAME, zoom both angles; on Steam, don’t trust the default angle—spin it. If both monsters grin back at you, pay up a little. If one side is a ghost, walk.
