Sentinel is a Tanky robot who can be a Rail gunner and an SMG.
can take a lot of damages.
can also be converted to hovers. ( i put some gap in some places to put hovers )
can weild upto 10 guns ( or more ) by just adding the rod in front.
triforced inside so plasmas will have a hard time killing.
damage testing video coming soon :)
Sorry for my bad english :]
