yeah, but neither is Jumping four-thousand and eight (2004 double-Jumps=4008 spacebar taps) times but valve seemed ready and willing to award player who did, EXACTLY THAT, with an achievement bonus that got players closer to the sandman, Bonk Energy Drink, or that small shotgun (this was in Team fortress two BTW)
On a different Note, More achievement Ideas:
Ghostbuster Kill the Nihilanth with a beam from the gluon gun
Chuck Norris Kill an ichthyosaur with a crowbar while you have less than 30 health
Redundant. Chuck Norris would never have less than 30% Health.
And if I recall, Nihilanth can only be killed with several explosions within it’s head.
Yeah I totally don’t even remember the Nihilanth fight except for the throwing satchels to the dude’s head. So the ending of BM will be a great refreshing treat for me 
I personally hated the Nihalinth battle. The whole thing from the combat to the teleportation chambers was one big fuck up if you ask me.
Or if you use the super powerful jump pad to propel yourself above him and shoot his brain. I’ve killed him with the crossbow and magnum this way.
This is also the only way to defeat him in Alien Mode, an unlockable in Half Life Decay.
None of the achievements in this thread will be used, save for this one – and it will be quoted word for word.
I <3 you, Eric Fong.
Last time I played through I jumped in his head and crowbar’d it to death.

Watch the video, Baconeggs. The Alien Mode ending shows the Vort that you control going from the Lambda Core teleport room to Xen with other Vorts bowing down to the Vort that you control. After that, the screen fades and comes up with the title Half-Life. You do not fight the Nihilanth as a Vort according to this footage. Besides, it wouldn’t make sense. You’re an alien slave of the Nihilanth, hence the cuffs on the wrists of the Vorts. Gordon Freeman is the enemy of the Vorts, not the Xen species or its master Nihilanth.
Not the alien campaign, I meant the alien mode unlockable, where you can play through the original Half Life as a Vortigaunt.
Mr. Vortigaunt, in the flesh - or, rather, in the… slave bracelets. I took the liberty of relieving you of your… electric abilities? Most of them were parts of your organism… As for the bracelets, I think you’ve earned it…
oh shi…
If only Black Mesa didn’t allow ridiculous nonsense like that…
Obviously, these vehicles of war should only be damagable by explosives. 
Strange… How exactly would this work in a game where you Load your last saved game when you die?
And energy weapons.
I dunno, I like saving my satchels and RPGs and just using the
9mmAR/handgun.
Those tanks are usually the only reason I use satchels.
So, you use small arms against TANKS and save up all your powerful shit for, what, headcrabs or something? Sense, you make none.
Alien Grunts, assassins, hell even normal grunts. If you can plink away at a tank without risking getting hit, why waste the good stuff?
An achivement for getting all achivements or seeing all easter eggs! (hope no1 came up with that idea yet)
Because it’s boring.
Well, boring as in it takes a 30 seconds or so to kill the tank, sure. But we’re not talking 10 minutes to do so. You can speed it up with the MP5 as well.
so of course you can kill tank with a pistol, but this is stupid and brings no fun, as you could never do this in real life…
