This Boss Fight is against the meme himself, Tachanka! He is an operator in the game Rainbow Six Siege. Tachanka has 3 phases: 1st phase- will fire a slow firing pistol at you. 2nd phase- will fire his faster firing LMG at you. 3rd phase- will fire his LMG at you and will shot a fire grenade at you. (Also, during the 3rd phase, barbed wire will appear. You will move slower if you step in the barbed wire.) WASD or ARROW KEYS to move CLICK to shoot. This fight has the Rainbow Six Siege Ammo Mechanics! Your magazine will have 31 ammo in it by default. If you reload (by pressing R) before you are out of ammo, you will preform a tactical reload and refill your magazine to the maximum. If you empty your magazine, however, you will preform an empty reload. This takes longer and only restores 30 ammo instead of 31. Not that you know what to do, go out and kill the Legendary Tachanka!
Thanks to Ubisoft for making such a great game!
