EDIT:

2 hours more mucking around and adding whimsical details, 'reworked' the legs, etc... lighter armour around the arms, added airlift rings that can be adjusted via its modular rail shoulder fins.. [can add missile pylons, etc]

+

4 hours PSCS2, no ref, airbrush tool, default brushset


Some nice ppl here asked for a series, so here is one image for the imagination... lots of ideas rolling in my head, but im trying to write them down and post the pics in the order intended to tell the little story!




Some additional info:
The Essa 4's head unit is slaved to the copilots/gunner and isn't a primary sensor suite at all -it is a pure turret. The 'eye holes' are firing ports for the twin CIWS [close in weapon systems] /20mm M61A1 Gatling rapidfire cannon that spew Armor Piercing Discarding Sabot (APDS), Depleted Uranium sub-caliber penetrator at 4,500 rounds/min. Due to weight constraints, ammo kept in the skull cavity is limited to 3000 rds that is shared between the gun units. In future evolutions of the Essa, they eventually phase out and become caseless munitions.

ERA plates /Explosive Reactive Armour is fitted on 'hotspots' on the upper torso. Found on modern day battle tanks, and from what I understand, these ingenius explosives essentially protect a surface by exploding at the point of impact by a foreign body, its own concussive force negating that of the intruding round, or even overcoming it and destroying it completely, leaving the 'parent surface unscathed. There are numerous technological variants of course, and the ones mounted on the Essa 4 are smartplates, so they do not rupture unless contacted at high caliber munitons muzzle speeds.

The tongfer/baton unit can retract and extend both ways along the underarm rails at extreme speeds. [With its size and mass alone, these babies pack a wallop on pretty much anything that gets in close proximity to the Essa. Future editions are explosive-powered and even carry their own submunition for a violent ravaging close-in blast.

Canister launcher-pods on the 'hips' allow firing from squatting [fire backwards of the Essa] and forwards on the move/uprighted. Ordnance options include smoke, illum/flare, chaff and Anti Personnel rounds.

Most of the Essa 4 is synthetic muscle, treated with reactive smart fabrics to boost reaction time and durability, not to mention lowering overall weight and being a solid successor to machined joints and servos. Muscles regenerate over time with nanotech-infused 'blood'. This lends an eerie air to the Essa, as pilots and crewchiefs tend to their "living" machines.

The backpack unit acts as a booster and primary energy supply for the muscles to be activated and react in tandem with the pilots sensations and movements. If depleted, the Essa can still maintain locomotion, slowly, but unsteadily. Hence leaving it in no shape for combat-oriented movements.

Lastly, there are no heroic wankers in this tale. (you know, the G.I Joe sort.) These are expensive machines and priceless lives we're talking. Combined arms and formation tactics rule the end days that humanity will soon come to know of. These titans are always at least in pairs, or have at least a detachment of Infantry Fighting Vehicles(with a full combat load) if alone, AntiAir gun tanks (like the one pictured above), refuel and recharge trailers in tow, and a AllTerrain Command Walker,[TAC Walkers] an enormous tactical Command, Control and Communications platform and base of operations housing command-level personnel and their retinue for any battle. These are lightly armed, and thus rely on the well-oiled combat drills and tactical decisions made as a Fighting Formation/Unit.
