Tomb Raider LAU Trilogy Speedrun in  

Well they kept the Mexico level trigger in the first level, of course I'm gonna go through it.

Yes, if the medpack spawns, that happens

I'm not starting with Underworld halfway done. I start exactly where the game starts. It's just that there's two triggers at the end of Prologue: one that takes you to Mediterranean Sea, one that takes you to Mexico, which is halfway through the game.

Here's a video that explains it, in case anyone cares enough to understand how the start of the Underworld run works: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8UWL3KTmdB8.html
