Role

Constructor working away

Constructors are devices similar to Sentinels in purpose, and Plasma Pistols in appearance, that mainly repair damage to any Forerunner structure they find, using weak energy beams similar to Sentinel Beams.

The Sentinels will come to their aid if they are attacked, as they are ill-suited for combat. However, their beams will damage someone if they get caught in the path (on legendary their beams can kill in seconds but still not enough for complete and devastating death). They also can use their beams to lower the shields on pistons, allowing them to move throughout the Sentinel Wall quickly. Constructors are encountered only during the level Sacred Icon & the Quarantine Zone (Level), but they can be seen on The Oracle.

When they appear in the Level known as the Quarantine Zone, they appear at the end of the level where the player fights Flood controlled Scorpian Tank and a Flood controlled Wraith Tank. Along with many Flood using Covenant Ghosts. Two Sentinel Enforcers fight agsint the Flood near a downed Human Pelican dropship. During all this chaos, if the player watchs one of the large and deep trenchs, a huge cloud of Constructors fly off into the sky.
