We have a separate discussion thread for each of the other skills under consideration, so the bazooker/mortar should have its own one as well
First, I want to list some of the decisions that could go one way or the other, so as to make clearer the range of possibilities we are talking about.
* The projectile could be fired horizontally (L2's Bazooker) or in an arc (L2's Mortar). Of course, we don't have to keep the L2 names in either case. The projectile could also be fired straight upwards or in a diagonal line, but I don't think those are under serious consideration; they seem to be strictly less versatile than either of the main options.
* For the Mortar, we'd have to decide on the size of its arc.
Strato Incendus seems to envisage the Mortar having a Jumper-sized arc (roughly 18 pixels up, 36 across), but I think
at minimum it should be double this, maybe even larger (such as 64/128). (Remember that skill shadows will aid with placement, so this should not be much of a consideration.) I don't know what the arc size is in L2.
*
The explosion could kill zombies, or all lemmings. (The explosion having a flinging effect as in L2 is
not under consideration.)
* The explosion crater could be differently shaped or sized, compared to the bomber's crater.
* The projectile itself, while in motion, is a unique object whose interactions should be considered. Does it explode when it hits a lemming or another projectile? Can it teleport? Does it bounce off one-way fields?
