A couple of objects which will give you a good start on a Celtic themed level.
Three transparent runes that will light up when Lara touches them.
Two switches with a rune on each of the two sides.
A big knot-shaped switch for Lara to push.
Four different monolith objects to build stone circles with – just like Stonehenge.
And of course a small set of stone, brick, moss and ornamental textures to start with. 🙂
If you use any of these objects in your level credit me (Nadine / Horus) and link to Tinulin.de in your readme file. Credit goes to http://www.obsidiandawn.com for some celtic knotwork brushes.
