Not quite as good as HL2 but very much worth a go.

Continues right where Half-Life 2 left off. A short yet amazing journey which involves you... Er, yeah, I'd rather not spoil anything.

It definitely won't take you any longer than 5 hours to complete so I'd say it's worth dedicating an afternoon to it. The gunplay still feels damn great just like the original game, though this time it's not even required - you can finish the entire game firing only one bullet. It won't make things any easier, rather the other way around, but yeah, if that's your thing, you can choose to do it.

A must-play for everyone who's played Half-Life 2 before.

ever since playing through Ravenholm in HL2, i thought, "I'd really like a game where i have to use the gravity gun the ENTIRE TIME". and behold, HL2E1 was brought down from the heavens upon me, and a task was bestowed: to fire one single boat through the whole game
