ok known stuff of Lineage Eternal:
- uses new game engine developed entirely by NCSoft
- sequel in Lineage franchise and is set 200 years in the future after the events of Lineage 1
- game is in development for 3 years
P.S has nothing to do with Lineage Forever that is rumored since year 2000
- on the game atm works about 80 people from the NCSoft Team Eternal
- game is using isometric play style (like diablo, ultima online, lineage 1 etc) camera can be also zoomed or turned around
- non-target combat system with use of new technology of hold n drag skills
- so far 3 classes known male knight & elemental (spirit) archer and female wizard (in plan are 5-6 classes)
P.S. if you watched the video towards the end you can see a 4th class another female mage class with black armor, silver/white hair and dark skin tone (god i hope its dark elf

)
- destructible environment (setting things on fire, exploding barrels etc)
P.S. most epic moment as it was seen in video by this is when the knight picked up the bowl of fire throws it on the tent and sets it on fire and then the mobs ran out all on fire

- interactive environment and it will have a major role in combat (like picking up objects and trowing them, climbing walls, using hooks to move, using levers for open doors etc)
- large scale sieges
- beta testing is set for second half of 2012
- game is developed as a global project (it was already confirmed that its planned to be released in japan)
