Publisher review:Unity is a unique game creation/editing utility that comes with one of the most impressive game engines on the market. It can be used to build next generation games with ease.
It allows you to include beautiful graphics, vast terrains and lots of trees. It also is compatible with NVIDIA PhysX, and comes with skinnable in-game GUIs.
You can deploy your project to any platform, including Mac or Windows, iPhone, iPad or the current generation consoles.
Requirements:
- Using Occlusion Culling requires GPU with Occlusion Query support (some Intel GPUs do not support that).
- Graphics card with 64 MB of VRAM and pixel shaders or 4 texture units. Any card made in this millennium should work.
Operating system:
Mac OS X 10.5 or later
