The Claymore is a non-canon melee weapon featured in some fanon maps.
Remember When...[]
The Claymore appears in the Remember When... storyline maps, Geist Wohnhaus and Einen Langsamen Tod. It is a wall weapon that replaces the Bowie Knife, Sickle and Machete from previous maps. It has a long effective range, but a slow slashing speed. Its high damage makes it great for high rounds. It can only be obtained through buying it off the wall.
Effectiveness[]
The Claymore is a good weapon for high rounds, due to its great damage. It is a one-hit kill up until Round 18, but starts losing its effectiveness afterwards. Due to the fact that it has a slow slashing speed, getting multiple swipes at an enemy can be difficult, however, the Claymore can take out multiple enemies at a time due to its long blade. The Claymore is useful up until Round 26.
