As all counts as models, they should not confer a modeling advantage over the standard Citadel model. Thus someone could feel free to use things such as the Mantic Zombie Marines or the Paulson Anime Railguns as they do not confer an advantage. It would even be OK to bring a WW2 Stuka model converted up as an Ork Dakkajet, as long as the model was roughly equivalent in size. Finally understand that if you are not bringing the current model, you may not gain any advantages but can still gain all the disadvantages.
Importantly ask yourself these two questions:
- Is this model abundantly clear what it is?
- Is this model very close in size to the GW model?
If you can say yes in both cases then it is probably ok. If you answer no to either question, then it probably won’t fly.
As with any uncertainty it’s imperative that you contact the event staff regarding any potential questions, or concerns. This is your responsibility as a player and a tournament attendee.
Q: What about Power Weapons?
A: Models that include a power weapon with no further special rules should be played as the model is equipped. You can model a different type power weapon but it must appear to be however it is played. You must denote the power weapon type in your army list and it cannot change throughout the tournament.
Q: What about Drop Pods?
A: If the doors cannot be opened, both players must agree before the game to either pretend, to the best of their abilities, that the doors are open and both players can see ‘through’ the core for line of sight purposes, or they can play that the model blocks line of sight ‘as is’ in which case the Space Marine player will be unable to ﬁre the Drop Pod’s weapon (a trade-off for the improved line of sight blocking ability of the model). Judges will assume the decision was made to see ‘through’ the core.
