Andromeda Survivors

As the description says, you need to level up any upgrade to max level, which is level 6. This will obviously require you to level to at least level 6, but expect to need to get to at least level 12 or 13 until the same upgrade shows up enough times to continue to level it. You can also spend some money you've earned to reroll your upgrades if you don't get the one you want, but I wouldn't bother with that until you're down to only one upgrade.

In terms of which to upgrade, I highly recommend the missiles. They're extremely good anyway, and fully upgraded they're amazing. Cannon upgrades are another I'd recommend. Refer to Endurance Champion (30G) for more tips on surviving long enough.
