Play as Wraith or Banshee, a pair of deadly assassins who spent years in training to become the efficient killing machines they are today. Only they are capable of wielding the new Assault Crossbow, Explosive Crossbow, and Synapse Scrambler. They terrorize their enemies with the Caution and Inner Focus Abilities.

Tear up the battlefield with these Assassin-specific weapons:
| Assault Crossbow |
| The Assault Crossbow holds 5 bolts, which can be used for single-shot accuracy or fired simultaneously for a devastating 5-bolt burst shot. Single Shots are extremely accurate, while the burst shot spreads to cover a wide area. This weapon does massive damage with the single shot, but accuracy decreases with consecutive shots, so allowing time to regain your composure is important. The bolt is visible as it travels through the air, forcing you to take the target's movements into account when firing. The Assault Crossbow requires a high degree of skill.

|
| Explosive Crossbow |
| The Explosive Crossbow slings explosive bolts that stick to surfaces and can be remotely detonated. Only one bolt can be detonated at a time, and bolts can be destroyed by enemies. There is a short delay between triggering a detonation and the resulting explosion, so make sure you time your shots right, or your enemies could escape unscathed.

|
| Synapse Scrambler |
| The Synapse Scrambler is a plantable device that assaults soldiers within its radius with a neurological attack, reversing their mouse controls and slowing their movement. The device makes a small amount of noise when deployed, and only one can be deployed at a time. The Synapse Scrambler is very visible and can be destroyed by enemy fire, but in the right hands it can render a group of enemies completely helpless.

Try out the Assassins' exclusive Abilities:
| Caution |
| A discerning eye allows Assassins to spot enemy traps and weapons, which are marked with a red indicator. Never fall prey to an ambush again! |
| Inner Focus |
| Assassins can sacrifice all of their Stamina to regain HP. They won't be able to regenerate Stamina until they respawn or hit a Recover Point, but their HP gauge will be full, allowing them to continue the fight! |
Something stirs deep within the Nemexis Lab. Gather your forces and enter the installation to discover the lab's secret!
Once you're inside, you'll have to clear each section of the building quickly as Nemexis soldiers pour in to thwart your efforts. But soldiers are the least of your worries. If you can make it past the first wave of Nemexis soldiers, you'll be confronted with the deadly weapons the facility has been producing.
Fight off the Nemexis-controlled mechs, and you'll get the chance to mount up in your own instrument of destruction! You'll find 4 different types of mechs:
| Melee |
| Using the Hermes melee weapon or an Athena pistol, this mech is meant for close quarters combat. |
| Sniper |
| Using the Artemis sniper rifle, this mech fires full-auto sniper rounds very accurately. |
| SMG |
| Using the Ares machine gun, this mech does a massive amount of damage, although the fire is a bit wild. |
| Medic |
| Using the Apollo healing arm, this Mech can heal other Mechs by entering melee range of them and hitting them with this welding torch. They also have the Athena pistol, allowing them to defend themselves. |
Use the mechs to take down the hordes of Nemexis soldiers, and prepare for a much tougher enemy at the end! Beat the match on Hard or Extreme difficulty, and you'll be rewarded with some robotic headgear.
