The Spikemore is a special variant of the Claymore exclusive to the Zombies map "Shangri-La". The Spikemore is visually a normal Claymore with the addition of Punji Stakes crudely attached to the front with what is presumably a kind of adhesive tape. It costs 1,000 points and works exactly like the Claymore.
It functions the same way as the Claymore, but it has Punji Stakes attached with fireworks that activate when tripped. The foot stakes seem to ricochet off walls once or twice after being fired. Spikemores are less useful then their counterpart, the Claymore, since Spikemores lose their one-hit kill ability at Round 25 and the normal variant at Round 27, although Spikemores have a wider spread, thus killing more Zombies. Spikemores refill every round after it is purchased like Claymores do in other Zombies maps.
