Half Life 2 Episode 1 Achievements

Half Life 2 Episode 1 Achievements 8,0/10 632 votes

As your train rides into the sunset, or wherever, you receive your well-earned achievement. If you played on Steam, you are now a better player than 99.2% or people who have played Half-Life 2: Episode One. (almost 50% of which didn't even finish the game at all, pathetic quitters).

In What The Headcrab! Episode 19 I talked about a post on Reddit that said that only 1% of people who have played Half-Life 2 had attained all of the statistics. I couldn’t find a page that said only 1% had all achievements but I suspect it was a play on the current 1%/99% theme in today’s world.

Then later that day, I was playing a single player mappack for Black Mesa called Small Lab and I started to get some achievements. The funny thing is that I haven’t even played the game yet and when I do, I might even have most of them attained.

I’ve never been a big fan of achievements but I understand their appeal. Perhaps we could have Attain November, just like we did last year with HARD November?

For those that don’t know, and I didn’t, I had to look it up, here are the achievements per game:
Half-Life 2 has 33, Episode One 13 and Episode Two 22. That’s a total of 68.

Here are my statistics:
Half-Life 2: 20 out of 33 (61%)
Episode One: 3 out of 13 (23%)
Episode Two: 17 out of 22 (77%)

Half-life 3

So that gives me a grand total of 40 out of 68 (59%). Where that puts me on the global total, I have no idea nor do I care. But I am curious to know either because we play mods we are more likely to have reached a higher percentage than non-mod players.

What do you think?

Anyway, here is a vote for your achievements.

What is your total achievements for HL2, Ep1 & Ep2?

  • There doesn’t seem to be a statistics page for HL2 – can anybody find one?

The Orange Box for the Xbox 360 has the most achievements of any Xbox 360 game with 99 of them.[1] However, it has only 1000 available gamerscore, whereas Gears of War 3 has the most gamerscore in a single game with 2000.

On its Xbox 360 release, The Orange Box received 99 achievements across all five games on the disc. On their release, the Steam versions of Half-Life 2: Episode Two, Portal and Team Fortress 2 all saw achievements. Until recently, for Half-Life 2 and Half-Life 2: Episode One, all achievements were exclusive to the Xbox 360. However, in the first days of the Steam UI Beta, all of the Half-Life 2 and Half-Life 2: Episode One achievements were shown on the game's Library/Games page. Users speculated that Valve would include those achievements for the PC, which they did on May 26th, 2010. The PS3 version has no achievements.

These achievements can be obtained in any game on the console versions, but can only be unlocked in a specific game in the steam versions.

Deadly Harvest Kill an enemy by planting a Hopper Mine. 5G Once the Combine start using Hopper Mines, Gordon may pick them up with the Gravity Gun. Plant one in an enemy's path so that it activates to kill them. (The achievement will not unlock if the mine is thrown directly like a grenade; it must be planted then tripped.)
Hack Attack! Kill five enemies with a Manhack. 5G Gordon must grab a Manhack with the Gravity Gun and use it to kill an enemy, either thrown as a projectile or held as a melee weapon. The achievement is cumulative; it is not necessary to kill five enemies using a single Manhack.

Conservationist Kill five enemies with the same Energy Ball. 5G Using the alt fire on the AR2 Pulse Rifle, or using the Gravity Gun to control one of many energy balls found in the Citadel (or one fired at him by an Overwatch Elite), this feat can be achieved by firing into a narrow area with 5 or more Combine soldiers and letting it bounce around, killing them. It is possible to catch and fire the same ball multiple times.
Think Fast! Kill an Elite Soldier with his own Energy Ball. 10GElite Soldiers will sometimes fire an energy ball at Gordon. When one does, Gordon must catch it with the Gravity Gun and fling it back.

(On occasion, the achievement can unlock as soon as you enter the area.)
Two Points Use Dog's ball to make a basket in the scrapyard. 2GBlack Mesa East When Dog's 'ball' is available, Gordon needs to pick it up with the Gravity Gun and successfully shoot it through the large basketball hoop on the far wall of the scrapyard. A green light on the hoop will indicate success. It is worth noting that the ball only has to pass through the hoop, and it does not matter whether it is from the top or bottom. Players may find it easier to shoot the ball up instead.
Zombie Chopper Play through Ravenholm using only the Gravity Gun. 25G'We Don't Go To Ravenholm...'
