Xenoblade Chronicles/Outer Space

At this point, you can't warp, you can't go back and you can't save at all since this section is the finale. You'll be encountering planets and unique monsters you have beaten earlier, as they pass off as spirits which should be easy to handle.

Dealing with Zanza involves three stages and the fact that you can't daze him. The first involves his crew which also deals with chain attack. The next stage is straightforward. The third involves Shulk having the true Monado. Use that to give him the final blow.

The final cutscene involves the things that happened before, between Zanza and Meyneth, out in space where the big bang happened. Alvis is a computer and Shulk decides to live in the world without gods. You'll see another cutscene from a point of view from Fiora before revealing herself as human again. Of course there would be credits as well.

If you dread of starting a new game and doing everything again, don't fret! There's a new game plus with few exceptions worth mentioning, your character levels, branches and party affinity carries over, including the true Monado and also clothes your team is wearing at the last moment. Along with other things that can be carried over but the map, quests and many others will be reset. When you finish choosing what you want, don't forget to save so the next time you play, you won't have to sweat it anymore.
