Portal Stories: Mel is a mod consisting of 21 maps with various themes, linked together by a strong, brand new story. There will be new voice lines, models, materials, particle effects, challenging puzzles, and much more! We estimate players to spend 15-45 minutes on each level, making the total time playing the mod 4-12 hours, depending on experience. Most levels consist of puzzles with varying difficulties. The difficulty will always be in the puzzles. The execution will never require any quick reactions.
