I got an idea to add another upgrade, namely a grenade launcher. You can shoot grenades like a spidertron. Hold LMB to aim. One shot takes one energy. This upgrade is available after "Energy capacity 3". Also, the grenade will be painted in the same color as the human. But this perk will be blocked. You need to complete "Spidertron Challenge". This challenge contains 10 levels, in each of which there will be a spidertrons, and in the last levels you need to defeat SPIDERTRON-10000(The info about this enemy written in the previous topics)
