It took some work, but I finally got a sub-2 run! Since the last uploaded run, I learned the infinite grenade glitch and the 3-6 skip. I also spent time tuning routes for individual levels.

Notable Mistakes: —Missed the grenade throw in 1-3, causing me to lose my opportunity to destroy the transport early, costing me about 30 seconds. —Forgot to bring a Heavy Machine Gun to 2-5, so I couldn't get that clip. —The game froze during 2-6 and 3-4, costing me about a minute total (I had too many Chrome tabs open, I closed them once I realized what was going on). —Died a couple times to the final boss, losing me about a minute.
