What's new in 2.0.1
Co-op for up to four players
Every player is a full hero: each of the four has his own hero with that hero's own weapons and ranged weapon, moves, combos and combo names, health, ammo, Perfect meter, upgrades, experience and levels. What each player earns goes to his own results and upgrade screens and into the save, so his unlocked combos and upgrades carry on to the next level.
Every player's own HUD: health, experience, Perfect meter and markers for players 3 and 4 too, with the Fair / Good / Excellent / Perfect rating and special move names on each player's side of the screen (players 1 and 3 on the left, players 2 and 4 on the right).
Each player's device: P1 Device to P4 Device (the keyboard and mouse, or a controller). In play each hero answers only to his own device;
Each player's controls and rumble: players 3 and 4 have their own controller layouts, and their controllers vibrate.
Weathertop: every player has a torch for the fire, so all of them can fight the Nazgul.
The story's levels stay open once the game is finished (completing the Hornburg Courtyard counts). Credit to [Volverine-Dude](https://github.com/Volverine-Dude) (PR #18).
Versus for up to four players
Team Deathmatch: players 1 and 3 against players 2 and 4.
Free-for-all: three or four players, each for himself (Player 4 Plays: Yes / No).
Troll Battle for up to four: Player 3 Plays and Player 4 Plays. Players 1 and 3 are the black cave troll, players 2 and 4 the grey one.
The match's board: hold F7 (player 1) for the round, the rounds left, and each player's rounds, kills and deaths.
Results for every mode: every player's rounds, kills, deaths, kills per death and most kills, for Team Deathmatch, Free-for-all and Troll Battle.
A fallen player stays down with his death animation until the next round, then gets up.
Health pickups: About 3 to 5 for each map, can only be picked up when damaged.
Kicks off ledges count: a player kicked off a ledge or off the map is out, a kill for the kicker. Walking or falling off on your own just puts you back on the ground.
No leash: every player can go anywhere on the map.

Linux Fixes
The dedicated graphics card, however the game is started: with NVIDIA's driver the NVIDIA card is used/selected first; on a PC with a second AMD card beside built-in graphics, the AMD card is used/selected first. TT_NO_PRIME=1 leaves it to the system.
MSAA with fog and snow: the Gates of Moria's fog and snow show with MSAA enabled.
The F5 launcher: F5 on the main menu opens the launcher (mods, language, settings), and Play starts the same build again (It could switch to previous settings before) with the new settings, mods included.
Other Fixes
Launcher settings apply from the first start, on a fresh install (Windows and Linux). Graphics settings set in the launcher now stay applied upon first launching the game.
The game closes completely when you quit the game or it is shut down, no process is left running in the background.
