A 7th anniversary special/collectors edition of the Lineage 2 MMORPG is being released in Japan next month (08.05.11) and besides the new weapons, game art, and soundtrack that usually go with this type of release it's going to include a special Siege Golem papercraft.
This Siege Golemn model is designed by Shunichi Makino. Collectors can buy one from Amazon Japan when it becomes available, suggested retail price is 5,040 yen ($62). If you don't want to buy and just get a copy of the papercraft you can always try this Siege Golem version from Teksukamen - is free and looks closely similar ^^
Update: I've been told by some readers (North America-based) that they can't access the lineage2.plaync.jp URL, it looks like it's region locked. You might want to use a proxy server / service (e.g. Anonymouse.org) to view their site.
