Ashassin's Creed Chronicles: China is the first game of three in the Chronicles spin-off series based on the main Assassin's Creed franchise. It is a 2.5D platform game similar to the earlier Assassin's Creed II: Discovery . The game is set in China in 1526 with Shao Jun as the protagonist, a character that was earlier introduced in the short film Assassin's Creed: Embers .
The game has a linear side-scrolling design, but with a lot of vertical movement. At times it is possible to move to a plane in the background and Jun can hide in alcoves or pass unnoticed by hanging from ledges. The game brings over the parkour movement of the main series with jumping, crouching, vaulting, sliding, sprinting, platform sections and more. Although a combat approach is possible, the game encourages the use of stealth.
Enemies have a visible awareness cone based on line of sight. Next to white that shows the reach of their sight, there is a yellow state where guards investigate and a red state where they alert others and attack. Jun has a large amount of abilities to wield stealth. She can take cover in alcoves and assassinate from there and assassinate from ledges.
Jun can assassinate with a hidden shoe blade, but she can also engage in regular combat with a sword using mechanics to perform two types of attacks, block and roll over. It is also possible to block backwards and dodge bullets. Various gadgets are unlocked gradually, such as daggers to trigger wind chimes or attack from a distance.
After each level a number of upgrades can be unlocked. There are also secondary objectives and optional hidden collectibles. The game is presented as an Animus simulation so Jun cannot die, but desynchronizes. The Animus database is also present where descriptions about people and locations are stored as they are encountered.
Additionally, the game features plus and plus hard mode which can be unlocked next to normal mode. Existing abilities and upgrades are carried over, but in plus hard for instance Jun has only a single health bar and enemies react faster.
