Most built-in or USB keyboards work fine.
We recommend a USB gaming mouse for PC and Mac. Mac users should look for a dedicated gaming mouse as the Apple Magic Mouse doesn’t have dedicated left/right buttons and a scroll wheel, which are usually needed for games. Logitech and Razer offer many different options.

• Sony DualShock 4 for PlayStation 4 (USB wired and Bluetooth)
• Logitech Gamepad F310/F510/F710 Note on Macs you must change the controller to work in (Direct input mode). On PCs you can use either mode

• Xbox 360 and Xbox One wired controllers
