There is an action game called ETHER VAPOR Remaster that are available for sale on STEAM client right now and Libellulium here is one of the mecha/character.
The game is a 3D arcade shooting made popular in Japan where you control your ship/mecha fights in a war between Lydia against Caldea . The game is sold around $7 at my place.. Quite cheap.
As for the template it came in PDO and requires 3 sheets of paper to build. The difficulty is 4/5 however it should be easy enough compared to building a Gundam model.
