From Halo Bulletin 8-15-12:

Engineer Specialization: Spartan optimization for the subversion, repair and reconstitution of a wide range of technology, including Covenant and Forerunner complex networks.

Drop Recon Armor Mod: Armor mod allows users to predict the location and time of an Ordnance Drop through an external suborbital monitoring system.

The Drop Recon armor mod – the helmet of which has four socket connections for add-ons, depending on the task – lets you know that Infinity Ordnance is coming and what the Infinity Ordnance is. You see the waypoint and type of weapon that is coming down prior to the weapon entering the game (the specific time is still being fine-tuned). Organized teams will find this armor mod useful because, with communication, there is the likelihood you can beat everybody to the weapon spawns your team finds most desirable.

HFFL’s thoughts:

Objective: The Engineer’s mod gives you the tactical advantage of knowing the location and time of an Ordnance drop.

Subjective: Okay, first I’m really curious if we’re able to switch mods during games? If so, this one could be useful a little later in games as people start to rack up more kills. During the beginning of games it’s kind of useless since Ordnance drops occur when people tally up a specific amount of kills.

Armor: The armor looks “strong.” Though the helmet, for which I put the heaviest amount of criticism on for all of these specializations, doesn’t quite work for me. Why that little “Brazilian” strip of a visor? Rather that whole are where the four circles are and the visor could have been a bigger visor, thereby highlighting the helmet more.

Emblems: The emblems for this specialization fit it to a “tee.” I like the screw emblem the best of the Engineer emblems.
