While the trio of Doom games were in rough shape on Switch when they first arrived (yikes, Bethesda logins!), that lunacy has been patched out, and Bethesda has continued to patch the series. This time around, we're getting a hefty update for Doom and Doom II.
All versions now have access to the community mod BTSX Episodes 1 and 2, Nightmare mode "has been restored" to make enemies twice as fast, widescreen rendering support is in, a crosshair can be enabled for more precise aiming, just like the original and a ton of bugs have been squashed.
In an interesting turn of events, the iOS port is getting a new touch scheme and controller support, but more importantly, the PC/Switch/PS4 editions are getting gyro aiming. Bethesda calls it an "additional amount of precision," and you can either set it to the controller's pitch or yaw. Or, you can turn it off. Bethesda notes that on PC, the only way to currently use gyro aiming is to hook up a DualShock 4.
