Deus Ex Machina in an exploration into a fan remake and modernisation of the original in Unity, redesigning systems and game mechanics to conform to modern iterations of the franchise and the genre as a whole. Not designed to be an exact remake of the original but instead and evolution of it with the intention being at this early stage to produce a reimagined Liberty Island as a portfolio piece.
Generally these fit into a category where they are recognizable in most major films and games. While doing that they also fit really well in a cyberpunk setting and that of DX and in reality are incredibly potent weapons. As per the previous point regarding older weapons, there would still be enough of them around in 2052 to still be making an impact, and therefore should be represented.
They would have to be included into the weapon pool as rarer weapons that the player can use, or that are found in select areas and inventories of key people. Can also be purchased on the black market for a premium.
