Portal Prelude: One awesome looking Portal Mod!
So I stumbled upon a while back on a blog called Portal Prelude. Portal Prelude started out as a personal project that focuses on days before GladOS (think a unoffcial prequel).
Its story revolves around the pre-GlaDOS epoch,before she was plugged in. At this time, test subjects were monitored by real Aperture Science employees whose work was tedious, lengthy and repetitive (and didn't tempt you with Cake). This is why they decided to build a great artificial intelligence that could both replace them in these difficult tasks, but also take responsibility for many other tasks within the complex and compete with Black Mesa's superiority
The mod team is going all out, including captions for all of the original voice work that they did (well voice snyth, but still impressive). The Portal Prelude team also included tons of new test chambers as well. And the best part? Portal Prelude will be absolutely free! I will grab the mod as soon as it comes out and give it a try and post a review then. They will release via http mirrors and a few BT trackers, so hopefully it won't take too long to actually grab.
The mod looks pretty awesome and comes out in like 6 or 7 days. You can find more info at their website, www.portalprelude.com
