Best way for 2D Tiles based level

Hi people,

I need to make a small to medium levels for a game like in NEs old days.
Unity don’t have a tile map level editor, so it is a way to use 2D Tiles and keep a good performance for the game ? What is the best practice for 2D Tiles based (squares and diagonal shapes collisions and tiles ) games with Unity 4.6 ?

Theres a unity plugin called “2D ToolKit”. It has really good performance and can import tile-sets made in Tiled (or other software). It’s not 100% going to cover everything, but if you need tiles, it does the job.

Thanks.
