These are the top 4 Unity games :-
Rust – Rust was inspired by games like DayZ, Minecraft and Stalker. It is a massive multiplayer game (currently up to 300 players per server) where you and other players are attempting to survive through the awful conditions, where humanity has been reduced to cavemen.
Rust’s world is harsh. The environment is not kind. Bears and wolves will chase and kill you. Falling from a height will kill you. Being exposed to radiation for an extended period will kill you. Starving will kill you. Being cold will kill you. Other players can find you, kill you, and take your stuff. Fortunately for you, you can kill others and take their stuff. Or maybe you can make friends and help each other survive, using the game’s building tools to create a safe haven. We provide the tools. How players survive is up to them.
The Forest – Build, explore, survive in this terrifying first person survival horror simulator. Enter a living, breathing forest with changing weather patterns, plants that grow and die. Tides that roll in and out with the day/night cycle. Below ground explore a vast network of caves and underground lakes. Chop down trees to build a camp, or start a fire to keep warm. Scavenge food to keep yourself from starving. Find and plant seeds to grow food.
Build a small shelter or a large ocean side fortress. Decorate your home with found items. Lay traps and defences to keep a safe perimeter. Explore and build during the day. Defend your base at night. Craft weapons and tools. Bunker down during the evening or bring the fight directly to the enemy.
Besiege – Besiege is a physics based building game in which you construct medieval siege engines and lay waste to immense fortresses and peaceful hamlets. Build a machine which can crush windmills, wipe out battalions of brave soldiers and transport valuable resources, defending your creation against cannons, archers and whatever else the desperate enemies have at their disposal. Create a trundling behemoth, or take clumsily to the skies, and cause carnage in fully destructible environments. Ultimately, you must conquer every Kingdom by crippling their castles and killing their men and livestock, in as creative or clinical a manner as possible!
Overland – Overland is a tactical survival roadtrip game in which players protect and guide a changing cast of characters on a roadtrip across a hardly-recognizable America. An environmental catastrophe of incomprehensible proportions has permanently changed the earth as we know it. Players scavenge fuel and other supplies as they head directly into the heart of the cataclysm. Meet new people and leave them behind. Overland is the first internally-developed game under the Finji label, and draws on a variety of influences, from X-COM to Oregon Trail, Edward Hopper, and biomorphic abstraction, to create a completely new experience for desktop and tablets.
