Played on Saturday and was told the following;

pulse wave goes through blocking terrain,

if one segment of barrier is attacked, it all comes down and

flyers in base contact with others flyers can't use RCE.

I know the first two are false, but is the third one also?

I think some of the guys I played against on Saturday are using their own house rules.

All three are incorrect.

Hope that helps.

I hope this was not a judge that told you this. Take a rule book and an FAQ with you.

Actually, one guy is a "stand in" judge when his roommate can't make the tournies.

Yes, all three are wrong.

On the case of the third point, flyers can make ranged combat attacks at any time, based or unbased, on any figure in their range. Even if a flyer is based, he/she can fire on any figure in range within line of sight. If you can make a ranged attack, then you can use RCE.

It was my understanding that a flyer who was in base to base contact with two grounded enemy figures was not able to make a range combat attack.
Did I get this wrong?

Yes.

Wow, has it always been like this or did they change it sometime ago.
Im a bit out of the loop on some of the rules kinda stopped playing after explosion came out.
Trying to get back into things now.
What about a grounded figure attacking a flyer at base to base, thats still a range attack right?

The ranged combat attack rule has gone through a couple different incarnations.

Any two figures which are adjacent can make close combat attacks against each other. So a non-flyer and a hovering figure that are adjacent may make close combat attacks on each other.

Assuming the flyer has LOF on the non-flyer it can make a ranged combat attack on the non-flyer. (Stealth would prevent LOF for example.)

The non-flyer can make a ranged attack on the flyer (assuming LOF) as long as the non-flyer is not also adjacent to an opposing non-flying figure.

Good to know, thanks for the input.
