Hey, I've got a few players who frickin love A.O.T and I was wondering if anyone had some cool ideas about how I could use the Genesys system to make a short, couple of sessions one shot type thing for them? Looking for ideas on how to make use of ODM and fighting Titans and stuff.

If this has already been discussed, then my apologies! I'm new here! If it already exists could you link me to it?

Thanks!

I think the ODM might work well as a Silhouette 1 vehicle:
Use Piloting to maneuver it about, moving at much higher rangebands than a normal human can run. Should have not that great of a handling, with players having the option of picking talents to improve it, as well as adjusting the gear itself (personalized gear with the straps properly adjusted would handle better).
The swords could be integrated weapons, but used with Melee(Light); and posessing either the Limited Ammo quality, or the chance to break on 2/3 threats, requiring an action to reload/attach new blades to the hilts.

Titans are a bit tricky, since they are unable to die unless you hit the nape. Might require some special ruling about requiring an aim/called shot (two setbacks, as per Genesys p.98).
With combat progressing at high speeds, and the speed of the ODM requiring frequent maneuvers (to turn around and back again as their speed keeps them moving past the Titans) players won't often have the luxury of two aim maneuvers, therefor making an actual kill very challenging (and keeping in the style of the show with that).
Normal attacks are of course still possible, and triggering criticals for instance can be very worthwhile, crippling their movement with cut tendons or blinding them with precise strikes to the eyes.
