Yup this is very true. I wish i had held off. quick question... I have found the Heavy Mutons very rarely if ever miss, which is a bit galling as my heavy cannot hit a barn door. anyone else have the same type of thing?
For those at a certain point in this game, don't be too hasty to build the hyperwave beacon. This locks you into a nasty choice, you're between a rock and a hard place. Either you shoot it down (assuming you have a Firestorm) and face ethereals and elite mutons and generally harder UFO missions for the rest of the game, or you don't and it keeps escaping, pissing panic all over the shop and damaging your council rep. You're kinda screwed either way. I tend to pause at this point until you have at least one and a half ninja teams and a good part of the kit.
