Angels Online or Angel Love Online (ALO; simplified Chinese: 天使之恋; traditional Chinese: 天使之戀; pinyin: Tiānshǐ Zhī Liàn) is a free-to-play PC and PlayStation 3 2D massively multiplayer online role-playing game developed by UserJoy Technology in Taiwan, and published by Q Entertainment.

It's free to download and uses the same pay-per-item model as its PC counterparts.

Once the player finishes the tutorial, they are teleported to the campus of the Lyceum where they can accumulate student credits on campus by doing lessons (composed of either defeating a certain number of a monster or collecting/manufacturing a certain amount of an item).

When a player graduates they become an Angel Protector and choose a faction and city.

Players are able to change or match skills after having chosen a class, which helps make characters distinctive.
