Severonickel is the last mission that took place in the Russian series of this game that was entirely deleted in the final release. For this leak, the entire mission is completely playable despite not available to access normally. It also contains the Nuclear Power Plant level but was crashed as you proceed somewhere in both parts.
It was played and recorded under the intention to stealth around the level as quiet as possible. Since this game was played on Xemu, I even make quicksaves just as the I did on the PC version. It is possible without it, but does not allow for the two Russian missions in this leak. I even used thermal goggles to make the gameplay a little faster since the frame rate is near bad for this emulator.
The leak here was modified to access the two Russian missions here. Like the PC version, you can bind the keys to access weapons, gadgets and medkit which was done here on this video. I spawn disposable picks for the first part and the SC-20K for the next part. Do note that not every inventory can be spawned for both parts of the mission, such as the SC-20K. While you can in the second part, the first part causes the game to crash. On the other hand, disposable picks does not work in the second part.
