Are you looking for some 1v1, online, FPS, insanely fast twitch action, then Shootmania may well tick the right boxes for you? This game is being developed by the guys behind, yeah thats right, TrackMania.
What's the system requirements of ShootMania Storm? Well we asked the guys at Nadeo for their run down and this is what they said...
We are building Shootmania Storm on the same engine as the Trackmania 2 game and so we are looking at a very similar requirement level
Shootmania Storm Minimum System Requirements
OS: Windows XP/Vista/Windows 7
CPU: 1.5 Ghz or more
RAM: 1 GB
HD: 2 GB of free space
GPU RAM: 256 MB with Pixel Shader 2.0
GPU: Anything from Intel HD Graphics 2000, Nvidia ION or AMD HD 6310 upwards
DX: DirectX® 9.0c with video drivers
These requirements still might change a little bit between now and release.
