At last, OpenTomb now features actual triggers and interactive keyholes and puzzleholes.

OpenTomb was in a stage of intensive development for all the past year, but until now, we haven't touched the sacred ground of triggers and entities interaction. Now the time has come, and for the first time we can see interactive (yet very rough) environment in City of Vilcabamba. Consider this a milestone, because now you can really finish the level with a little help of noclip.
Unlike original Tomb Raiders, where we had predefined and hardcoded routines for each entity type, OpenTomb allows you to program every single entity in game - all the code is done in Lua scripts. There is more to follow - timed triggers, pick-ups - and, of course, inventory!
