The Witcher 3: Wild Hunt is more than "30 times larger" than previous Witcher games,] requiring players to sail by boat to some locations and ride by horseback to others. However, fast travelling around the areas of known locations is also possible. The Witcher 3 has been described as "20 bigger than Skyrim". Many actions the player performs affect the world; many of the quests have a number of options on how to complete them, and the outcomes differ. CD Projekt RED anticipates approximately 100 hours for the completion of the game, 50 of them belonging to side quests, and 50 belonging to the main story line.br br It is not necessary to have played the previous Witcher games to fully enjoy Wild Hunt. While similar to the previous Witcher games, Wild Hunt has improved on several aspects from past games. Combat revolves around an action role-playing game system combined with the use of magic. The fighting system has been completely revamped. Wild Hunt introduces some new mechanics, such as witcher-sense, combat on horseback and at sea, swimming underwater, and using a crossbow. Additionally, Geralt can now jump, climb, and vault over smaller obstacles. The climbing mechanics have been described as "not exactly" like Assassin's Creed, but more "similar to what we have in Uncharted". Item creation and potion brewing still remain as in previous games, but have been modified from The Witcher 2. There are 10 witcher signs, 5 original ones, each having 1 alternative form.br br The game features advanced AI and responsive and dynamic environments. The day and night cycle influences some monsters and their powers, similar to how a werewolf would gain powers during the night of a full moon. The game also features a dynamic beard growth system, in which the beard of the playable character Geralt grows as he travels between regions. According to the developer, the beard grows "in different states". However, this feature will no longer be available if the player has downloaded the free Beard and Hairstyle DLC. Ciri, an exceptional swordfighter with mythical powers, is a playable character in the game. Gwent is an in-game collectable card game.br The Witcher 3: Wild Hunt concludes the story of the witcher Geralt of Rivia, the series' protagonist, whose story to date has been covered in the previous versions. Continuing from The Witcher 2, the ones who sought to use Geralt are now gone. Geralt seeks to move on with his own life, embarking on a new and personal mission while the world order itself is coming to a change. Geralt's new mission comes in dark times as the mysterious and otherworldly army known as the Wild Hunt invades the Northern Kingdoms, leaving only blood soaked earth and fiery ruin in its wake; and it seems the Witcher is the key to stopping their cataclysmic rampage.
