The wall is a reccurring boss in the Contra series. It is also one of the most iconic bosses of the series and appears in almost every single Contra game, usually as a miniboss on one of the early or later stages.
The Wall is a tall blue, black, green or grey wall mounted with blaster cannons. In the middle of the wall, towards the bottom, there is a glowing weak point. There is almost always a respawning sniper or two positioned on top of the wall. However, its appearance
The wall's attack patterns vary by game:
The wall fires from it's blaster cannons, the projectiles fall to the ground in an arcing motion. The sniper will shoot you much more accurately. While the sniper can be killed, another one will respawn in a few moments. There is also a turret on the hill in front of the wall that poses the same threat as the sniper, except that it won't respawn.
Same as the NES version, except the projectiles are replaced with bombs and the sniper does not respawn. The blaster cannons can be destroyed in this version, leaving the wall defenseless.
Contra III: The Alien Wars:Edit
Identical to the Contra (Arcade) version. Except enemies can come from offscreen.
Contra: Legacy of War
Contra: Shattered Soldier:Edit
The explosions from the bombs are now much bigger, making this version a bigger threat. The sniper also respawns in this version. Enemies stream in from off screen as well. This version has only one blaster cannon to deal with.
This version has two phases:
Phase 1 - Acts exactly like the Contra (Arcade) version. However, it can now fire a laser from its core.
Phase 2 - The wall suddenly erupts from the ground, revealing a second core. The first core also regenerates, requiring you to destroy both of them to destroy the wall. The bottom half acts just like phase one, but the top half has four snipers rather than one. Both cores can fire the laser now, and could potentially catch the inattentive player off guard.
Behaves exactly like its Contra III incarnation.
Hard Corps: Uprising:Edit
The wall appears twice in this game.
First encounter: The blaster cannons are not functioning, but the wall retains the laser attack from Contra 4. An extra gun is added allowing it to fire another laser at the higher platform. The sniper does not respawn if killed. The bottom laser is thicker and therefore more dangerous.
Second encounter: The bottom laser is replaced with large, fast moving energy projectiles. The sniper respawns if killed.
