Identifying NES game

[Glademaster_v1legacy]

I need help on identifying a NES game I had ages as I cannot remember the name and I'll give as much detail as I can.

It was a Shooter side scrolling.
It could be 2 player.
The characters look like robots(well they were to me).
The enemies are alienesqe creatures with a boss at the end of every level(8 if I remember correctly).
Any help also I know I said robot and it is not Metroid.

Probotector? The European censored version of Contra?

Contra?

There were about 9000 contra clones, define "alienesque"

Because there were alien games.

Sounds like European Contra to me :\

We have a winner thank you very much I couldn't for the life of me remember the name of that game.

No problem, I know more classic games and the histories than I really care to admit. *Stamps NERD on own head*
