Here is the current -- and quite tentative -- list of events 40K Origins is planning on running this Origins.
Main Events (One time events):
The World's Largest Apocalypse Game -- Friday all day
The Second Annual Origins RTT -- Saturday all day
Table Events (Running off and on all weekend):
40K Space Hulk
Tyranid Attack
The last event is a new one where a group of Imperials must attempt to beat back wave after wave of assaulting Tyranids. It is modeled after movies like Starship Troopers or Zulu.
We would also like to run a third table game. One possibility is the afore mentioned English Civil War demo, but this table is still up in the air. We want it to be a demo game where everything is provided, so it ultimately has to be limited to what we can produce/have. However, at this point we are willing to take any suggestions. So, suggest away!
