'''Operation Crimson Hammer''' is an [[Mission#Expansion_Missions|Expansion Mission]] that can be unlocked with a purchase of the expansion mission for $5.95. Challenge the mighty Warmaster Seerus in his terrifying Grand Arsenal and unlock unique mission rewards: the powerful Rocket Hammer and the shadowy Dark Retribution bomb! 

It was introduced to the game in the [[Release_Notes_2012-02-29|2012-02-29]] release. One of the Knights on the account must have completed the [[Mission#Rank_Missions|Rank Mission]] 3-2 'The Pioneers' in order to be eligible for expansion missions.

Once eligible, select the Expansion Mission you wish to purchase from the Expansion Mission menu and select 'Purchase Expansion'. Steam users will be taken to Steam and Web users to the Energy Depot to complete their purchase.

Purchasing an Expansion Mission unlocks it for all knights on the account.

==Lore==
[[Warmaster Seerus]] is the evil master of munitions within the gremlins' all-powerful Crimson Order. Thought to be the true mastermind behind the [[Roarmulus Twins]] and countless other gremlin weapons, he is the Crimson Order’s creator and supplier for their diabolical engines of war. 

Recon Knights under the command of [[Feron|Lieutenant Feron]] recently discovered Seerus’s ‘Grand Arsenal,’ his development center and storage facility for all his weaponry. Now, Feron himself has lead several squads of knights directly into the Grand Arsenal, with the intention of weeding out Seerus and destroying his war machines. 

Met with heavy resistance, Feron’s squads require reinforcements and [[Spiral HQ]] sends several knights to aid them in their assault.

===Aftermath===
'''Monsters'''
*None *

<nowiki>*</nowiki> There might be corpses of Gremlins and destroyed Battlepods, but they aren't counted.

Aftermath is a [[Treasure Floor]]; there are no active monsters, and [[loadout]]s may be changed anywhere, so [[heat]] from the treasure boxes here can be applied to any equipment in a knight's arsenal.

==Notes==
*<nowiki>*</nowiki> Note that in addition to the regular tier's Gremlin Thwackers and Gun Puppies, picking up the bonus key in the level after clearing the shadow fire blocks will cause 2 Gun Puppies and a Gremlin Thwacker one tier higher than the current to spawn. Therefore an [[Ironclaw Thwacker]] will spawn in Tier 1, and a [[Darkfang Thwacker|Darkfang Thwacker]] in Tier 2. Tier 3 is unaffected.
*<nowiki>**</nowiki> In the arena, the Tier 2 version of these monsters appear in Tier 1. In Tier 2 and 3 alike, the Tier 3 version appears, and has a fire status variant, namely the [[Gun Puppy#Red Rover|Red Rover]], [[Mecha Knight#Firo Knight|Firo Knight]], [[Retrode#Hotrode|Hotrode]], and [[Lumber#Redward|Redward]].
*Almost all Gremlin Mortafires are replaced by [[Mortafire#Blazing Mortafire|Blazing Mortafire]]s in Tier 2 and Tier 3.
*All Battlepods of Operation Crimson Hammer can cause [[fire]] status in all Tiers.
