Ok i'll start with an easy, yet common topic as the jet lag is still pretty heavy.
Crafting materials -
Depending on the scheme you start off with a set amount of materials. You can also deconstruct weapons from the first turn of the match to get more. This means that if your turn isn't first you can have a craftable weapon ready by the time your first go comes around.
You also get random amounts of crafting materials from crafting crates (the ones with a yellow cog on).
Crafting weapons aren't gated by things like kills etc. However if a weapon like the 'Airstrike' has a turn delay on it and you craft one, this crafted weapon will be effected by the turn delay the same as the default loadout one.
So the 3 Ninja ropes:
Ninja Rope - Standard Ninja Rope of the game, using recycled code from Armageddon for an authentic, yet new feel.
Ninja Rope Pro - A slightly suped up version with infinite swings and a longer rope.
Newbie Rope - The Armageddon Rope incarnate, I even feel it has slightly more control. (OPINION)
