Seeing one out of the corner of your eye is, again, more affecting than having someone sit you down and tell you everything about them. That is what the whole plot of the games is about keeping the portals shut so the true Combine army can't come through. At several points in the game you catch glimpses of Stalkers human bodies gruesomely retro-fitted with alien technology, turned into mindless slaves. And as you learn more about the invaders' infrastructure, the extent of their assault on the planet becomes chillingly clear. This kind of environmental storytelling continues throughout Half-Life 2, painting a more detailed picture of everything that happened while Freeman was on ice. Having just been yanked out of stasis by the G-Man, he knows as much as you about this bleak, Orwellian nightmare world that is, ‘not much', which only adds to the unsettling mystery of how Earth ended up like this.

This is more effective than an elaborate, expensive cinematic showing the Combine invasion of Earth would ever be, and puts you on a level playing field with Gordon Freeman. It's everything you need to know in one unassuming texture file-but also, importantly, it leaves enough of the finer details out to let your imagination run wild.
