Psionic Assault is an advanced micromanagement challenge. With a force of six high templar and eleven sentries, the player must stop a horde of zerg, protoss and terran attackers.[1] The difficulty increases as reapers join the fray.[2]

The winner gets a bronze achievement for killing 75 enemies, silver for 150 and 225 for gold.[1] Enemy units continue spawning after achieving 225 kills until 300 units are slain; no achievements are awarded for this, it is just a test of player skill.


1. 14 zerglings 2. 10 marines 3. 7 zerglings and 4 hyralisks 4. 13 marines and 1 marauder 5. 8 banelings, 1 roach, and 16 zerglings 6. 3 marauders and 10 marines 7. 23 zerglings (first south-east wave) 8. 6 zealots and 5 sentries 9. 10 reapers (north-east) 10. 6 reapers (south-east) 11.


Distribute energy use among multiple units instead of draining a few units completely dry. This maximizes the usable energy over the entire challenge by having multiple units recharge. In the early waves, rotate the units used for casting.


Block the ramp with the sentries' force field. Marines and hydralisks may be handled by one high templar casting psionic storm. Two high templar may be used against the marauders, which pose a more serious threat to the sentries.

Engaging from the top of the ramp may allow the sentries to engage without risking return fire. Using the sentries' attack may save energy for later waves. Use guardian shield as necessary.


Waves come from multiple directions. Conserve the high templars' energy for psionic storms on the reapers.

Against the zealot and sentry waves, erect force fields at the bottom of the ramp, and destroy the enemy sentries with the high templar's feedback. Maintain the force field wall to give friendly sentries time to kill the zealots.

Use feedback against the Banshees. Distract the Banshees with hallucinations early if the aircraft cannot be destroyed early.

Use four zealot hallucinations to distract each reaper wave. Destroy the reapers with psionic storm.


The high templar will be low on energy after the reapers. Create two archons from the lowest energy high templar.

The first attacks are by zerg attack against the destructible debris. Use archons and sentries to attack, and create hallucinations when the wall falls.

The Banshee waves may be handled as before with feedback.

The terran wave includes ghosts. Use force field to control the wave and use feedback on the ghosts. Create more archons as energy runs out. The last wave required for gold are two siege tanks in siege mode. However, if not approached they will unsiege and move towards the remaining protoss units; their poor pathfinding AI will prevent them from actually reaching the force if the sentries attack them over the ledge.
