Can you get it running here without external software?

In case anyone is wondering, I bought the game and did the test myself: all keybinds can be set to controller's buttons, also mouse tab has the "enable gamepad" option plus sensitivity settings for better aiming. You have to do your own setup, but that's pretty quick. Still, some actions will need a mouse, like navigating around menus, conversations, using the armory, hacking doors etc...

Overall, I'd say it's mostly playable with a controller, with a little mouse support :)
