Alien Trade-In: 500 UFO Debris per crystal
Alien Trade-In shows an exchange of 500 UFO Debris for one Alien Mutation crystal, with a 15% chance of successful application. Buying the crystal does not guarantee application. The 15% is neither an income multiplier nor a chance of entering a UFO.
Alien Mutation and Abducted: two labels, one record
The exchange interface uses Alien Mutation, while the announcement names the mutation Abducted. StealEgg keeps them together in the existing Abducted record rather than creating duplicate mutations. The income multiplier already recorded on the site remains ×2.50; the trade screenshot confirms the price and application chance, not a new multiplier.

Estimate income with Abducted
Abducted contributes +1.50 above ×1 when combining mutation bonuses. Starting with an egg income of 1B/s without mutations, Abducted alone estimates 2.50B/s. With Nitro ×2.75 as well, the combined factor is ×4.25, giving 4.25B/s. The estimate assumes successful application and does not apply size or weight again.
