When you kill a gecko does it count as killing enemies?

May be...

No, killing unmanned weapons like Gekko and Scarabs ( mini black spheres, really annoying enemies)DON'T count as a kill



In fact, you get bonus Drebin points for killing them, if you look in the right-hand corner, it'll say so



Oh yea, but killing the Frogs counts as a kill, and also, don't shoot the guys in the powered suits during Act 2

You can kill both the GEKKOS and the dwarf GEKKOs [annoying little black balls.



However on the chase sequence in Act 2 when you are at the mansion some soldiers come out in power suits and can be easily misaken for GEKKOS so look out.



You can also kill the unmaned flying things in Act 3.



But dont kill the FROGs.,

No, killing robots doesn't count as enemies. When you kill them you'll see on the right of the screen you get bonus drebin points and it says "destroy unmanned vehichle"
