It doesn’t say what IC stands for anywhere, so I picked my own. It’s probably not “integrated circuit”.
As we continue forward, we get more abilities. And as we get more abilities, there’s more upgrades to obtain. This will eventually peter out, but at the middle of the game (which is where we are now), there’s plenty to be had, which is why I spent half an hour just exploring every nook and cranny of Volt Forge. I’m sure I can do stuff like that in other places, but I’m of the mind that if I’m not losing all the time, I may as well continue forward so that I can fully clear things out later. Unless I happen to need to backtrack to the earlier area for something anyway, in which case I may as well do what I did here.
The fact that the gallery lets you rewatch stuff is cool, since it means you don’t have to replay the game if all you want is a refresher. It’d be nice if those simply appeared when I saw them initially instead of at completion milestones, but I’ll take whatever is available. I’m going for 100% anyway. The fact that the refresher on the initial planet only appears at 25% item completion is a little odd considering how much faster you get scans; you’d think the scan completion would unlock earlier items. Perhaps we’re going back there before the game ends? Everything we’re doing is on this planet, but Samus keeps getting flashes of a battle going on elsewhere. I wonder why that is?
