Grey Sentinel

Description
The Grey Sentinel is the standard, cheap, mass produced Sentinel. Even the most primitive group of mercenaries can afford to keep a small army of Grey Sentinels around to defend the entrances and such, although the larger outfits have little use for them due to their instability and weak firepower.

Variants
The Grey Sentinel comes in several standard varieties, each equipped for different tasks

Gunner
The gunner is a mid-range sentinel armed with a burst fire machine gun. It has very limited intelligence.

Lancer
Lancer's are agile short range combatants equipped with two blades in place of hands

Defender
The Defender is a heavy sentinel with small shields on its arms, it attacks purely through melee charges and heavy slams, however this leaves it unguarded

Grenadier
Grenadiers are heavy sentinels equipped with powerful grenade launchers.
