Confidential

Design
The Confidential has a black hexagonal base, and it looks similar to the Rogue Palisade. It has minion spawners at each side of the base, with a trap launcher on each edge of the base. It also has a symbol that looks the same as the AT4_BW and the unique Flangle variant when the message "Mladic won't be happy." appears.

Technical
The Confidential always deploys traps that doesn't do damage but "flinches" tanks (Similar to EMP, but does not slow down movement) for about 5 seconds, and minions that doesn't do much damage but inflicts the freeze effect.

Countering
As it always spins, and always deploys traps, try to use a builder branch tank or a long-range tank. You will need 1 Builder branch tank for defense, 2 if necessary, and a Ranger or Streamliner branch for offense. (Or Redistributors) Another method is using Kevlars. Kevlars are very effective against this boss as it is immune to all status effects, and it will melt down the Confidential's health slowly. 2 Kevlars is always enough for this boss, as the minions of this boss is the only ammunition, and the minions doesn't do much damage. The Confidential is quite slow in terms of speed, so focus on bullet stats instead of movement speed. Using lancers or flails is not an option, as the traps deployed apply EMP upon contact, and it is very hard to dodge the traps launched. The boss will either finish you off by slowly draining your health by its minions, or ram you as you won't be very likely to dodge the minions' freezing bullets. Using VPN won't help much. The minions it spawned will take damage for the Confidential as they spin around the Confidential.
