Re: AT LAST!!! A Battlez game arena that's not like having teeth pulled!
Your assumption is correct.
Having said that, my personal experience of the 'knock back' effect of the Primal Peashooter in Battlez is not that good.
Mine is at level 9, but it only seems to knock back a zombie with perhaps one shot out of 5 or 6 while playing in Battlez. Even then the amount of knock back varies, with the Zombies often moving back less than a column. When that happens the Blover often fails to shoot the zombie right off screen. (This is even when spamming with the Blover imitated, so the wind effect is virtually constant.)
When using it in the Adventure mode it seems to knock back once in three times and almost always hits the Zombies back around 2 columns.
Perhaps when I eventually get it up another level it might become more effective for me in Battlez.
