There were various Land Raider Proteus models on display at Warhammer World.
Mechanicus tech-savants believe that the Land Raider Proteus is a precursor to the Phobos pattern vehicle now found amongst the armouriums of the Adeptus Astartes. Bulkier and faster than the Phobos, ancient and forgotten data-looms describe the Proteus as a forward assault vehicle, commonly fielded in Explorator missions during the dawning days of Mankind’s fledgling galactic empire.
Those of us who have been playing Warhammer 40K since it was first released will recognise this model. It is of course a new version of the original Land Raider that was released back in 1987 following the release of the 1st edition of Warhammer 40,000, Rogue Trader. Forge World did release a resin version over ten years ago and this is the model on display above.
There was also this variant Proteus with armoured hull mounted dual lascannons on display made from the new plastic kit.
This variant can be made from the Horus Heresy plastic kit.
It is similar to the armoured Proteus which was announced back at Games Day 2011. However it is missing the sponsons.
