Annihilation (Level 100) – Earn 3 Quad Feed medals (4 uninterrupted kills in the kill feed) – 2,500 XP
On our list, this is one of the toughest challenges this season, especially because Scorestreaks do not count towards Quad Feed medals.
In addition to playing as aggressively as possible, you may find this objective slightly easier by changing up your Multiplayer playlists to either Hardcore or objective modes, or ideally both.
Eliminating someone in Hardcore is much faster compared to regular Multiplayer, making Quad Feeds potentially easier to earn for someone with quick reflexes. As for objective game modes, such as Domination or Hardpoint, they usually have more predictable engagement-heavy zones on or around objectives, giving you better chances to earn a Quad Feed.
Rigged to Blow (Level 110) – Get 10/20/30 kills with Proximity Mines – 6,000 XP (Total)
Proximity Mines are often best used when placed on objectives or in chokepoints and entryways with few alternative routes.
For example, on Express, think about placing mines at the top of the ladder right outside the Control room, or right at the door of the Ticketing room inside the main terminal. These areas see frequent action across all game modes, but see even higher traffic in Hardpoint where both of these rooms serve as Hardpoint hills.
Scrambled (Level 120) – Kill 10/20/30 enemies scrambled by your Counter UAV or Jammer Field Upgrade – 6,000 XP (Total)
Counter UAVs are a fairly low-cost Scorestreak, making this challenge rather easy to complete. If you want to complete this quicker, take the Jammer along as a Field Upgrade and place them where they are most effective: in secluded spaces, such as in a corner or around other small objects, within high traffic or objective areas.
For this objective and any other ones involving Field Upgrades, consider running the Gearhead Perk, as it will reduce the charge time on all Field Upgrades to let you place them around the map more frequently.
