It is possible (although very rare, but I got that once) to get 8000 points pecking order in the boss battle by shooting all the asteroids in the correct order (when Bossa Nova spawns them out). These are infinitely spawned enemies, so “Pecking order” and “Multikill” should not be awarded (Multikill is already disabled, but not Pecking order).
The asteroids do not disappear if you destroy the Bossa Nova while it is doing that attack (so it is possible to crash into them).
I just noticed something…normally,when we use special weapons,multikill bonus gets disabled. However,there’s something interesting with damage amplifier…if you use an amplifier in one wave,then finish it before it expires,and if you kill stuff in the next wave while it’s still in effect(unless you use another one in this wave),multikill bonus doesn’t get disabled for that wave. Perhaps multikill should also be disabled whenever you actually kill something while amps are in effect.
Behaviour confirmed, but as it stands it’s very hard to fix.
Nevertheless, disabling multi-kill for all special weapons made sense when the only special weapons were missiles/mines (which do indeed damage the whole screen). Perhaps a better solution would be to still allow multi-kill for the new phaseout/damageamp/shockwave?
In UCO encounter, it’s quite weird that the barbequer has no effect when it is fired in the middle of a green laser beam. It only takes effect on the frontmost part.
