There is only 1 weapon, the Flamethrower, cops light if within 14m (new update will be 15m) then they run away, they don't die, and new cops come to replace them. In terms of what to do is see how it can seem overwhelming. Its an arcade / puzzle game at its core, basically burn as much as you can as fast as you can, but I will work on making that more obvious and maybe a tutorial. Thanks for the feedback.
