Fun fact- the Welsh word for making, gwneud, sounds just like grenade

What in the drek-headed naming convention-
This is a dumping ground for a few possible "interpretations" of the rules on grenades.

What we know:
IRL grenades typically kill within 5m and wound within 15m.

Shadowrun grenades are less punishing, but measure things out meter by meter. GM no like extra work, so GM want to avoid this.

Possibility A: Mostly Rules-compliant
Throwing a grenade is a AGI + THROWN WEAPON (3) check. On a success, you win! On fail, GM simplifies rules and rolls a d8 to see which direction it goes.

If the grenade is within 2m, it is full damage. 4m is half damage. 6m is quarter damage. Beyond that is 0 damage. (Frag grenades may use 3/6/9m instead).

Like in the normal rules, you can take a -5 hit to your initiative to use movement speed to run away from the grenade. Or dive on it if you're Captain UCAS or something.

Possibility B: Less Crunch, Pl0x
Throwing a grenade is a AGI + THROWN WEAPON check. Anyone within 5m of the target location must beat your score with their REA+INT to dive out of the way.

On a glitch, GM rolls a d8 to decide where grenade goes.
