Central Online

Central Online (formally Crossover) is a cross-platform online gaming service from Clever Interactive that allows users to communicate with other users through their friends list, earn and view achievements, play online multiplayer sessions, and saving game progression through the cloud to be synced with multiple devices. The service is integrated with the Central service and can also be used in games on other platforms that support the service.

Crossover (2019-2022)
The service was first developed by Centennialville Studios, an Indian game development studio that specialised in developing cloud systems for video games. It was originally a division of Laserium Entertainment's Laserium Game Studios under the name Laserium Game Studios Hyderabad before being acquired by Clever Entertainment in 19 April 2015.

They began to start working on the service in 2018 as Clever saw the potential of a gaming service that allowed players to play with other players from multiple platforms and also saving their game progression to a unified network. This was during a time when cross-platform play became more mainstream as games like and  added cross-play with full support from the console manufacturers  and  with only  refusing to allow games on  consoles to enable cross-platform connectivity.

The service was announced by Clever as Crossover that allowed users to play online multiplayer across different platforms and can save their game data to the cloud to be played on a different device. Players have to sign into their Clever ID on a supported game to enable Crossover functionality, with a software update being required in order to enable it.

Crossover was launched on 23 February 2019 alongside the software updates to enable it. These games that supported the service at launch included Clever All-Stars HoverKarts Racing, Milkys Vs. Bluiens, War Flights, Flopo, Flopo in Colour World, Nuclear Island: Trap Run, Crimestoppers, Microsoft Sam The Video Game DX, Microsoft Sam: Rocket Race 2, Mixels Team Race, and Marbles The Game DX. At the time, due to Sony's objections to cross-platform connectivity between non-PlayStation consoles, the PlayStation versions of Clever’s games did not include Crossover functionality. This was until public and developer backlash caused Sony to start allowing developers to implement cross-platform connectivity to their games in which Clever pushed out software updates for their games on PlayStation that had Crossover originally on other platforms.

Months after the service launched, Clever announced it would open Crossover to third party developers for them to support the service and its features in their games using the Crossover API.

Later, it was announced by Clever that the service would be getting achievement support and a dedicated smartphone app that allowed users to communicate with users through their friends list, create parties and view their achievements and their friends achievements. The Crossover app was released for, , and on 15 August 2020.

Central Online (2022-present)

As part of Central Online being integrated into the Central app, the Crossover app was immediately discontinued with the mobile versions being replaced with the Central mobile app.
