On mission 27+, if you destroy all 9 planes(4 ofnir,4grabacr, and 1 mig 1.44 REPLICATOR)with at least 1 minute left, Archer will say "I just remembered its my birthday next week. it will make my mom happy when my brother gets back" then Swordsman will tell Archer to go make his mom happy by returning too. i think that is why Swordsman says "we gotta stop this thing" to Archer, not Blaze. In order to do this, i recommend you use a plane with SAAMs or XMAAs. when head to head with the Belkans, use 1 SAAM, switch targets, use anoher, switch targets, and as soon as the first SAAM fills back up, fire. then quickly switch back to regular missiles and kill the fourth grabacr. then go after the rest of the planes. if they seem to spread out, fly away w/o hitting the brakes or throttlefrom them so they follow you. pull the plane up toabout 20 degrees and hit the brakes. when they fly past you fire missiles and guns. if you destroy them with about 2 minutes left on the timer, Replicator will pop up very small in the middle of the map. he will be flying very fast.
