Hey, been a bit since release. This is a pretty large update to Dead Signal, hence the 2.0 label. The 2.0 update finally introduces Nightmare difficulty, aims to reward player skill with currency that can be used to take more control of a run via the new upgrade shop, and adds some highly requested features.

A greater challenge awaits those who've unlocked Nightmare by completing Normal difficulty. The Breather(threat) has been added to this mode. Difficulty has been increased across the board for everything. Completing Nightmare will reveal a secret meme ending, honoring those who triumph over the challenge. But be warned the mode is unfair, you'll need to master the ins and outs before you could ever dream of earning the God Gamer achievement for beating Nightmare.
Now players earn currency for completing tasks. Currency can be spent in the DarkDrop shop, which sells software (downloaded) and hardware (needs to be picked up on the roof). These upgrades vary in strength based on their cost and either help combat threats or upgrade the camera system. Some of the most common run ending situations can be mostly safeguarded against with select items from the DarkDrop shop. Purchased hardware will show a tool tip on pick up that shares the installation location. Additionally when you get close to the placement location with the item in your inventory a pulsing yellow hologram of the device will appear to make installation easy.
A switch outside the elevator on the roof has been installed. If flipped it will greatly increase the elevator's speed, however there's a 1% chance to snap the cable and cause death on each traveled to floor. Use it when needed, then turn it off to keep your future elevator trips death free. You'll see the largest benefit on long elevator rides. With the override switch on you can go to the lowest floor and back to your apartment in less time than it'd take to only go to the lowest floor with the standard elevator speed.
Three cameras from a laundromat have been added to the camera feed. There are new events to be reported that fall under the original six report categories.

A new character, Axecrypt enters your messages at the start and equips you with a hacking program that gives the option to either hack or report electronic devices. Hacking a device will offer a larger currency reward than reporting, but it can't be reported after. Likewise you can't report an electronic device, then hack it.
A new character, Lotus has entered your messages and has an optional task for you to engage with. In the report tab you're now able to switch the recipient to either "The Shade" or "Lotus". Switching to Lotus and sending a valid high value report will result in a sizeable currency reward, but the event will no longer be reportable to The Shade for a quota point. Likewise if you report to The Shade first you'll no longer be able to report that same event to Lotus.

There's a new device in your apartment that can greatly increase the speed of reports and camera malfunction repairs if placed in a hotspot. You can find it on a shelf next to the PC desk. Installing it in any of the apartment hallways is beneficial, though the better the spot, denoted by color(Green (strong), Yellow (moderate), Red (weak)), the more noticeable the difference. This device will change in status throughout the night, so moving it around will be ideal. Once you pick up the device from your apartment press [V] to toggle placement mode, then press [V] again while there is a hologram of the device to install it. You can pick the signal booster back up by pressing [F].
Translations have been made for the five most requested languages: Français(French), Deutsch(German), Polski(Polish), Português Brasileiro(Brazilian Portuguese), and Türkçe(Turkish). You can change the selected language on the main menu by opening the Options menu -> Game settings -> Language. In-game you can change the selected language by pressing [ESC] -> Game settings -> Language.

If you wanted to play with a controller now you're able to do so.

As of this moment the review process is ongoing, but it's been tested and functions correctly on Steam Deck in this 2.0 build.

Now larger screen resolutions (3440x1440 21:9) can play Dead Signal seamlessly. Those with super ultra widescreen resolutions (5120x1440 32:9) may not look the best, but are supported.
