Sonic Advance / Sonic Adventure Battle 2：2合1策略指南僅限

Finally found a guide that covers both Sonic Advance and the Battle 2 stages in one place—the level-by-level breakdown for the latter saved me hours of trial and error. The layout is clean and easy to follow without being cluttered.

I was stuck on a few of Sonic Adventure Battle 2’s later levels, and this guide’s detailed boss strategies finally got me through without any frustrating backtracking. The clear maps for Sonic Advance’s special stages are a nice bonus.

Having both games' walkthroughs in one book means I finally stopped juggling two PDFs on my phone. The section on the Chaos Emeralds in Adventure Battle 2 saved me a ton of backtracking, and the layout is easy to flip through mid-level.
