An Assault with Rapid Fire and Lightning Reflexes or Ghost Armor can be useful for scouting or dislodging entrenched enemies. A Heavy with HEAT Ammo and packing a Blaster Launcher will be able to deal some serious damage at a couple critical sections. That said, a Squadsight Sniper is extremely advantageous to bring along as most rooms offer decent perches from which to pick off enemies. Archangel Armor is less useful as the mission requires constant advancement and the map's various bulkheads and doorways restrict extreme range shots and general flight movement. You're going to want everyone toting the very best equipment: Plasma weapons, Alloy Cannons, Titan Armor and Ghost Armor. You're going to want to take all your best soldiers, preferably all Colonel rank. This is the final fight, it is long and all the hardest enemies are going to be thrown at your squad.

Unlike most missions in the game, the Temple Ship Assault features predetermined groups of enemies whose positions are fixed, becoming discovered or spawning as the player's squad progresses through the ship. In areas that don't have a central, highly elevated pathway, full cover is available, making it easier to perform frontal assaults with close-combat units, such as shotgun-equipped Assault Class soldiers. For a substantial part of the mission, there is a central pathway available that is positioned higher than either of the side pathways. Nearly every area in the ship features multi-elevation environments, which can benefit the player if soldiers are always positioned at a higher vantage point than the enemy.

The layout is also very linear, all paths parallel, leading in the same direction. The Temple Ship layout is predetermined, and consists mostly of pathways with guardrails that serve as cover.
