Constructor
The Strogg Constructor provides vehicle support through repairs and defensive support through turret deployables. Similar to the GDF Engineer, the constructor is also required to complete build objectives on a number of maps, such as the mining laser on Area 22, Ark, and Salvage. The constructor is also the counter to the GDF Soldier's ability to plant an HE Charge on a map objective; the constructor can disarm the charge before it detonates requiring the soldier to plant another charge in an effort to complete the task.
Equip the constructor with either the lacerator or nailgun. Reaching the first experience reward unlocks the plasma launcher, which turns the lacerator into a combination Strogg assault rifle and plasma launcher (use the alternate fire to switch to the plasma launcher). Although this can make the constructor more combat capable, your primary duties are repair, deploy, and construct mission objectives.
Position defensive turrets carefully. Place anti-personnel turrets along likely GDF ground troop routes and anti-vehicle turrets along likely vehicle routes.
The constructor's build objectives take time; request cover from Strogg Aggressors and support from Strogg Technicians (supplying Stroyent cells used for health). Take advantage of terrain vehicles or vehicle to provide cover from GDF attackers. Strogg Oppressors can also use their long-range fire support to eliminate attacking GDF troops while your constructor works on completing the build objective.
When the Strogg defensive maps, the constructor should call in a defensive deployable to aid Strogg forces against GDF ground forces, vehicles, and artillery projectiles. Each constructor can have only one deployable at a time; if you choose to build a second deployable, you will be prompted that the first will be destroyed. The constructor should utilize the Strogg anti-personnel turret to counter GDF ground forces; the Strogg anti-vehicle turret to battle GDF vehicles; and the Strogg artillery interceptor turret to counter incoming GDF artillery, rocket, and missile projectiles.
The chart below reveals experience rewards for the Strogg Constructor. The first reward unlocks an additional weapon, the plasma launcher (it becomes the alternate fire mode for the lacerator). The second reward allows the constructor to target Strogg vehicles or deployables and use flying drones to administer repairs. Finally, the constructor receives increased rate of special abilities—faster construction and disarm and self arming mines.
| XP | REWARD | DESCRIPTION |
|---|---|---|
| Level 1 | Unlock Plasma Launcher | Adds the plasma launcher attachmenet to the lacerator. Use the alternate fire button to toggle between modes. |
| Level 2 | Target Flying Repair Drone | Allows the constructor to use flying repair drones to repair remotely. |
| Level 3 | Faster Construct and Diasrm | The constructor can complete build objectives and can disarm GDF HE Charges faster. |
| Level 4 | Self Arming Mines | Constructor's mines no longer have to be manually armed with the repair tool. |
Oppressor
The Strogg Oppressor is a support class with the ability to deploy long-range fire support, much like the GDF Field Ops. Utilize the long-range fire support to aid in both offensive and defensive situations. Bombard attacking GDF to help your Strogg teammates defend a vital objective or use the long-range fire support on the defending GDF troops to weaken the defenses and open the way for your Strogg forces to assume control of the area.
When the Strogg are on the offensive, the oppressor needs to target GDF deployable defenses with fire support, such as the Strogg Rail Howitzer.
Use the oppressor's artillery deploy tool to call in a rail howitzer, plasma mortar, or dark matter cannon. Like the engineer, field ops, and constructor, each oppressor can have only one deployable at a time. If you attempt to place a second deployable, you will be prompted that the first deployable will be destroyed before the second one will build.
The constructor's turrets fire automatically but the oppressor's fire support weapons have a recharge rate. Choose your shots carefully; a complete miss means waiting for another chance to fire while the GDF forces attack or defend unscathed. Likewise, be careful not to create friendly fire casualties with your artillery strikes. Check the radar carefully to ensure you aren't hampering the Strogg forces with your bombardment. Killing your Strogg defenders just to eliminate a couple GDF attackers will likely have disastrous results. Have teammates clear any GDF artillery interceptor turrets from your target location before firing.
