Defeated the 15th and 16th Colossus, and cleared the game in normal difficulty (also endured being sucked into the light for over 1 minute in the ending).
Survived the Train Sequence, got through the first Zero-G area, survived the first encounter with Stalkers, killed the Tormenter, won the fight at the School, defeated the AI, and completed the Solar Array Puzzle.
Completed Factory, Emporia, Comstock House and The Hand of the Prophet. Finished the game in 1999 Mode without purchasing anything from a Dollar Bill vending machine.
