Do you like liquid simulations? Do you like the flow behavior of water? Do you like bomb explosions? If yes, then you will have much fun with the Physics Sandbox app. [by gaming-apps.com] Three physics simulations in One: 1. Shipping / Raft Survival: You can build your own ship or use a pre-builted boat and try to survive, if you go on a raft trip with your boat now. 2. Powder Game: If one use the real-time sandbox, then you can play with our bomb simulator or simulate diverse states of waterbody under different influences in every areas of the room. Furthermore you can build for example a house and let it explode later. 3. Liquid simulator: One can watch various structures, ships, buildings, dust etc. and they interact together in different forms, if you insert prefabricated user-actions like a spawner... into the Simulation. Features: - this game is free! - a) sandbox, build for examle a wall and throw bombs to it (Powder Game) - b) raft survival (shipping mode) - c) 24 prefabricated level designs (simulation mode) - construct your own boat with 13 different single parts of a ship - 6 prefabricated levels in the section "shipping" - one can add to a own constructed boat 4 prefabricated - furthermore: 5 bombs types + 5 upgrades per bomb with different explosions - 4000 water particles (soft bodies /powder/ dust) - watch the general behavior of fluid, e.g. pressure, flow behavior, spread in the observation room, special effects, etc. - build and control your boat - create various structures like a house, a seesaw, a tower ... be creative And now have fun with our free physics game everybody! by gaming-apps.com This game is free, but shows ads.

The toughest prison sim in the yard is back to serve its 3rd consecutive sentence - combining classic moments from the OG with the best aspects of 2D, while putting out a few hits of its own! See how long you can survive in a sprawling facility, where hundreds of fellow prisoners are trying to get through each day in real-time. Develop relationships with an advanced dialogue system that allows you to start conversations before the drama comes to you. Should you choose violence, a combat system perfected by wrestling lets you express yourself with your fists! Hundreds of fully interactive props can be equipped in either hand to dual wield as tools or weapons - including mind-blowing gunplay that allows you to shoot at ANY moment. Reinforced by a creative crafting system, you've only ever run out of ammo when you've run out of ideas. Just when you think you've seen it all, a whole other police role challenges you to tackle crime from the other side of the fence - keeping existing prisoners in order while patrolling the streets for new ones! An extended outside world makes life worth living, with a wider range of vehicles and animals to explore it. All now presented with higher resolution visuals, a smoother frame rate, and a wider variety of camera angles to enjoy cinematic moments. Upon upgrading to the fully "unlocked" experience, an inbuilt editor empowers you to save your changes to each character to make the world your own. You can then blow off steam in a special "Fight Scene" mode - where you select WHO fights WHERE and with WHAT! The action can also be enjoyed at a smoother 60fps frame rate on compatible devices, with no ads for paying customers.
