Why content in games is limited? Well because time, staff and money is limited. Especially with IOI recently.

Also it's free, you don't allocate huge resources into something you give away for charity, like they did. Guns all feel like new guns anyway, due to the upgraded sounds. Everyone probably has heard what they say about free gifts...

You still have the old unlocks in the old game, so install that... if you simply can't touch the legacy pack. The "GOD DAMMIT they expect me to actually PLAY the free remastered levels, with better graphics, AI improvements, working mirrors, foliage, better camera logic!?? They expect me to actually PLAY it? THIS IS OUTRAGEOUS" whining is getting pretty tiring. Kind of also discrediting IOI for the massive favor of remastering it and giving it away for free. As if it's nothing but unlocks to you, fuck the improvements.

Don't like it, don't play it, move on.
