While I personally enjoy finding all this naturally on my own, there are some items on this list I wish I knew about a little earlier compared to when I found out. Like Hot-keying weapons and aid took me a little bit to realize on Xbox, I also haven’t gotten as far in the main mission as they suggest, so who knows, everyone has different styles on how they play.
But still take it off in stealth missions, as the invisible spacesuit still increases your noise level.
