传送门1里结尾的那个机器人。
没有激烈的打斗，没有宏大的场景，没有精彩的对话交锋（倒是有单方面的被开嘴炮，因为主角不说话orz）。
其实玩到最后一关看到那个机器人的时候有的只是惊讶而已，连震惊都算不上，但是精彩的是在通关之后。
结尾的那首小歌，滑稽的腔调，优美的旋律……还有令人毛骨悚然的歌词，都给我听哭了。
听完这首歌之后那天晚上我疯狂的找传送门1、2，半衰期系列的背景故事，那才叫是宏大而壮阔。在之后我就去补了半衰期1和2的游戏，那就是后话了。
没玩过游戏的同学光听音乐可能没什么大得感触，建议玩玩游戏，绝对不会后悔的。
因为一个逗比的boss爱上一首歌，被安利了两三个游戏，还改善了我对G胖的印象，也算是令人印象深刻了吧。
有兴趣的可以听听这首小歌，p1就是：

补一个歌词：
Still Alive
from HALF LIFE 2 - PORTAL
This was a triumph //这是一个艰苦的胜利
I'm making a note here: HUGE SUCCESS //我在这里写下了一句话：伟大的成功
It's hard to overstate my satisfaction //我的兴奋之情难以言表
Aperture Science //光圈科学
We do what we must because we can //我们因梦而尽力而为
For the good of all of us //为了我们中的优秀者
Except the ones who are DEAD //除了已经死去的人
But there's no sense crying over every mistake //不必为每次失败而哭泣
You just keep on trying till you run out of CAKE //蛋糕是你奋斗的力量之源
And the SCIENCE gets done //当这项科技完成之时
And you make a NEAT GUN //你会见到那洁白的传送枪
For the people who are still alive //这是生者的希望
I'm not even angry //我仍未恼怒
I'm being so sincere right now //我现在将心比心
Even though you broke my heart //即使你粉碎了我的心灵
And killed me //还毁灭了我的肉体
And tore me to pieces //把我撕成碎块
And threw every piece into a fire //将我焚烧殆尽
As they burned it hurt because I was so happy for you! //当我化为飞灰之时我感到伤心，因为我曾为你喝彩
Now these points of data make a beautiful line //现在数据汇成繁星点点
And we're out of beta //我们凤凰涅盘
We're releasing on time //获得新生
So I'm GLaD I got burned //我将自己献给了烈火
Think of all the things we learned //想想我们的知识
From the people who are still alive //那是生者的智慧结晶
Go ahead and leave me //勇往直前吧
I think I prefer to stay in side //我甘愿作为绿叶
Maybe you'll find someone else to help you //或许一天你会找到同道中人
May be Black Mesa //是黑山么
THAT WAS A JOKE //开玩笑的
AHA, FAT CHANCE //啊哈，想都别想
Anyway, this cake is great //不管怎样，这块蛋糕不错
It's so delicious and moist //甜美松软
Look at me still talking when there's SCIENCE to do //看看我，我一边说话一边进行研究
When I look out there, it makes me GLaD I'm not you //当我向窗外看去，我因不是你而感到快乐
I've experiments to run //我要做实验
There is research to be done //还有研究未完成
On the people who are still alive //生者就是小白鼠
And believe me I am still alive //我相信我还活着
I'm doing SCIENCE and I'm still alive //我因科学而存在
I feel FANTASTIC and I'm still alive //我因感知而存在
While you're dying I'll be still alive //我会看着你灭亡
And when you're dead I will be still alive //我永垂不朽
Still alive //不朽
STILL ALIVE //到永远
