The latest instalment in the wasteland survival series looks set to be one of the most hotly anticipated games of 2015, with retailers already confirming that pre-order sales are strong.

But with Fallout 4 coming as early as November 10, the idea that bumps could be encountered along the way have been noted by Bethesda, who also say they're confident that their small team of developers have managed to keep track of all the new features.

The tried-and-tested first or third person combat system is back with the new dynamic Vault-Tec Assisted Targeting System (V.A.T.S) that lets you choose your attacks but also comes with a few added twists.

Being able to build thousands of items in a new advanced crafting system means that weapons, armour, chemicals, and food can all be customised to a player's unique style.

And speaking on the subject of keeping track of all the new features and how they fit into the expanded world of Fallout 4, creative director Todd Howard told Gamespot: "We're lucky, in that nowadays we're not a very big studio--we're just over 100 people. We have about eight more people than we did when making Skyrim. Relative to what we're making, it's a tiny studio.

"But it's also the same team; this is the group that did Fallout 3. This is the group that did Skyrim. We're able to work with people that know our systems and design processes so well. We can complete each other's sentences. So that's how we get so much content, but absolutely, the hardest part is gluing it all together.
