I reluctantly downloaded the movie thinking it would be booring to just watch a guy play half-life for an hour, but this was seriously amazing! That dude exploited so many bugs that he practically skipped half the game!
Gotta love his treatment of "Power Up": enter level, run by garg, place tripmine on "impassable" wall, jump on tripmine and over wall, next level plz.
Or on "weve got hostiles" where he intentionally gets himself dragged up by a barnacle just to shoot it and fall off on a higher, much further section.
Or when he walks straight up the cliff face in the beginning of surface tension, runs along the top completely skipping the dam section, and jumps off the cliff into a wedge so he takes no damage.
Or in blast pit where he jumps AROUND the outside of the entire silo.
And thats only a few. Wow. just Wow.
