Assault Suit Leynos

To get this trophy you need to obtain 3 armor upgrades by earning an "S" rank on the first two stages, and equip them at the start of stage 3. Then at the end of the stage, wait near the Versis (the large ship on the far left) until the countdown timer runs out, but don't actually enter the ship. Zosaly will appear from the right, in a panic about being trapped outside. Stay as close to him as possible, paying attention to his green life bar, and you will protect him from burning up in the atmosphere. You need to have 3 armor upgrades equipped and not lose any of them from taking too much damage earlier in the stage, or you will both burn up on re-entry and the game will end.
