How to unlock the Double Dose achievement in Ultratron - Definitive Guide
This is not possible until level 50, which is the first level with 2 bosses. You can always restart at level 41 with all the upgrades and money you had at that point, if you fail to beat both bosses on your first attempt.
This trophy is earned by finishing a level where two bosses spawn that you must defeat. This occurs on every tenth level after you "finish" the game once after beating level 40. The first time you will fight two bosses will be at the end of level 50, at which time it will spawn the first two bosses simultaneously so that you have to fight both at once. This isn't very difficulty as long as you stick to the edge of the room to dodge them and make sure you are aiming for the guns to kill them. Once you have defeated both bosses you will earn this trophy.

After completing the first four bosses, the levels begin again, but with more difficult enemies. After the next 10 levels you will encounter two bosses at the same time. Eliminate them and the trophy is yours.
