For our full impressions, read our lengthy Assassin's Creed 4: Black Flag preview, and read below for the key information. http://youtu.be/j_oPTO-a4O0 http://youtu.be/IJ9N2hX9S0s Freedom underpins everything in Assassin's Creed 4. There are eight studios working on the game. Ubisoft Montreal is leading, with Singapore, Sofia, Annecy, Kiev, Quebec, Bucharest, and Montpellier assisting. AC4 is set in the West Indies in 1715, the world is totally seamless. There are 50 unique locations including cities, jungles, ruins, coves, and caves, all with hidden treasure and adventure. You can harpoon whales, go diving, and loot ships There will be proper assassinations with targets that you choose how to approach and take out. You'll fight against, and alongside, infamous brigands like Edward 'Blackbeard' Teach, Benjamin Hornigold, Calico Jack, and Anne Bonny. Major cities include Kingston and Havana, and there'll be dozens of smaller settlements and port towns scattered around the world to explore and pick up missions from. The new hero is Edward Kenway - father of AC3's Haytham. He is selfish, cocky, and charismatic. Edward owns his own ship, the Jackdaw. It can be upgraded, repaired, and customised, and you can manage her crew. As you sail the high seas you can climb the crow's nest and use a spyglass to search for ships on the horizon. This tells you how strong they are and what cargo they're hauling Weather and physics will play a larger role in naval combat There are different classes of enemy ship, including 'chargers' who'll try and ram you and shatter your hull. There aren't any interruptions in the transition between naval combat and boarding a ship You can approach ships from any angle, weaken them with your cannons, then attach grapples to pull them towards you and storm the deck. Or swim around the back unnoticed and slit the captain's throat for the stealth-loving players. Instead of Desmond, the modern day is centered around you, a 'research analysts' working at Abstergo and living out the past Edward Kenway, Many of the multiplayer modes from previous games will return It all looks fantastic. The waves are especially impressive, tossing ships around as lightning streaks across the sky.
