- This article is about an in-game mission. For the in-universe event, see Operation Gambit.
Lost Butterfly is the first mission of Ace Combat Infinity.
Goodfellow: Alright, time to start the briefing. We've got a new guy here today, but I'll have to cut the introduction short. My name's Goodfellow, and I'm your rep from the Arrows. As you know, Arrows is a mercenary force specializing in aerial warfare. Some people like to call us "pirates". I'd prefer they call us "privateers", at least. We are being employed by the UN Security Council, after all. Anyway, the UNSC's military staff committee just sent Arrows a request for deployment. It was originally going to be an escort mission for the UNF Pacific Fleet stationed in Tokyo Bay, but that's changed. We now have multiple unknown UAVs flying toward Area J4E, Japan's former capital of Tokyo. In other words, right here. The UAVs are likely armed. We need them downed before they reach city limits. This'll be the first sortie for the rookie here, TAC name Reaper. Here's your emblem. Omega from the Bone Arrow flight will be supporting you on this mission. Follow his instructions. I'll be expecting results, you hear? Dismissed.
The player has to shoot down nine UAVs within the time limit. The game sends up two UAVs, followed by one, followed by three, followed by three more. The last five UAVs are labeled as targets, but shooting them down does not automatically complete the mission. Once all UAVs are down, the mission will be completed.
An S Rank on this mission is likely achieved by completing the mission within a set time, but this cannot be confirmed yet.
Goodfellow: This is believed to be a terrorist attack carried out by armed forces from the Iyuli region. They've caused extensive damage to Tokyo. The naval fleet was also attacked, so the UNF generals are all furious right now. The UAVs they used are an upgraded version of the MQ-90 Quox, a Japanese-made UAV that's also been deployed in the Americas. It may be unmanned, but it's still a very powerful bomber. It's equipped with an aggressive aerodynamic design, and a new type of semi-automatic control system. The UNSC says it's a Wernher Noah product. Apparently the control systems are a top-secret design that they stole. Wernher denies everything, of course. Navigation would normally use a system that relies on improved GPS satellite tech, but this craft uses a different relay system for its operations. We also caught an unknown fighter craft flying at high altitude over the area. The UN's going to raid and inspect Wernher's facilities in Iyuli and the other special zones shortly. Wernher Noah is the biggest company in its field. Normally the UN doesn't like doing anything to make them angry. Now, though, I guess they don't have much choice.
