Assault Suit Leynos

To get this trophy you must prevent the Versis dropship in stage 3 from taking any enemy damage. This seems more difficult than it actually is. At the start of stage 3, advance slowly and carefully, destroying all the Zako (the small green enemies) before they can get to the Versis and attack it. A flashing alert will appear if an enemy gets close to the Versis, and the green bar next to the ship will start depleting if it gets hit. You will need to restart the level if it takes any damage.

Keep an eye on the scanner at the top of the screen, where the Zako are represented by small red squares. Make sure you have the booster equipped so that if any get past you, you can catch up to them easily. When you get close, a helpful red arrow will appear indicating in which direction you can find them. Once they engage you they will leave the Versis alone. You can also dip into the atmosphere and they will follow you and burn up, just don't linger there for too long.

When you encounter the huge dropship in the middle of the stage you shouldn't have to worry any more about enemies slipping past you and attacking the Versis. After the dropship is destroyed, head back to the Versis and hover a short distance in front of it, taking out any Zako enemies that get too close. Wait until the countdown timer hits 10 seconds, then land on the platform where you started the stage and re-enter the ship (unless you have 3 armor upgrades still intact and are rescuing Zosaly for the "A Friend in Need" trophy).
