Collects and sells user data with a very broad and vague description, including a note that they "do not honor DNT". Contractually it is set up that your data can be given to just about anyone for just about every reason such as analytics, marketing, targeting ads, cross device tracking etc.. It is explicitly stated that personally identifying information such as images, voice, name etc. can and will be collected

“This is how remakes should make originals feel insecure.” Black Mesa is what happens when fans remake a legendary game and somehow don’t mess it up. It takes Half-Life, cleans it up, polishes it, and then casually flexes on half the modern AAA industry. Gunplay feels tight, enemies are still annoying (looking at you, headcrabs), and the atmosphere is pure science-gone-wrong perfection. You don’t play Gordon Freeman
