This pdf is 4 pages long, 1 page SRD, leaving 3 pages of content, so let's check this out!
Helms of communal command were brought to NeoExodus by warriors from another world that had been fighting a war against medusas and similar creatures on their homeplane - devoid of slits, they grant immunity to sight-based effects like color spray and grant blindsight to the wearer. Up to 6 communal mind-helmets may be attuned to each other, granting a kind of collective perception between attuned helmets and a bonus ti initiative an AC for everyone in the network. Silence for example can suppress the helm's effects. Even better yet, Section Omega has created a psionic alternative of these helms, which can be fitted with cognizance crystals and are suppressed by catapsi-effects. Nice and wholly compatible with Psionics Unleashed!
The pdf comes with item cards for both versions.
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to the new parchment-style background and beautiful full-color NeoExodus standard, but we get o printer-friendly version. the full-color artwork of the helm is awesome. The pdf has no bookmarks, but needs none at this length.
The items are cool, the option to get a psionic variant is awesome and the idea behind the items and their minor weakness/possibility to disable them make them even cooler. Due to the low price and the provided variant, I'll round up from my verdict of 4.5 stars (which is due to the lack of a printer-friendly b/w-version) to 5.
