The Highway Spider (ハイウェイスパイダー Haiu~Eisupaidā?) is a miniboss in Contra: Hard Corps. It is a considerably large mechanical vessel in the form of an insect which can move along any surface at great speed.
Encountered in the tunnel section of the High Speed Fight stage. The Highway Spider makes its entrance by clinging along the tunnel's ceiling; it then skids along its walls until it comes to ground level, where it starts crawling at great speed while positioning itself behind the player, from where it starts firing plasma shots which must be jumped over. Afterward, it climbs back along the tunnel's wall and takes out a retractile mechanical claw, which it then launches bumping along the ground from right to left.
This mechanical creature is not particularly resilient, though, and it will soon succumb if the player consistently keeps firing at it.
