Fallout: New Vegas has received its largest modification, The Frontier, which adds a huge number of new quests, 24 thousand lines of voiced dialogue, new armor, and hundreds of new characters to the game.
The Frontier also brings over 150 new weapons to New Vegas—for which the modders took the trouble to create effects and record sounds—vehicles, and even dynamic weather changes.
The new quests are divided into three questlines, each of which can take an inquisitive player around 15 hours to complete.
Although The Frontier is free, running the mod requires the original New Vegas and all of its add-ons.
