to get 100% sync you suppose to no lose any health.
ive already done this like 4 times with full health, didnt lose any health squares at all. but the game still says i did, so i only get 50% sync.
is this a glitch or bug? ive tried restarting the xbox, and do the memory again without losing any health at all, and its still not working.
trying to get the achievement for 100% sync on AC and Da Vinci
