War Metal Armory

Article: The Outdated War Chip Units.

War Chip units experienced over time a devaluation in their power, but instead, they still have the same cost of War Chips.
Thus, units become outdated, weak and obsolete in its quality - price.
Although the developer should update their skills (statistics, effects, skills ...) or to reduce its costs so that, at least for collectors, some may be interested in buying, in most cases do not.

So that there are few old units Chip War that even today are still useful.
Some of these are:

Venomous Raptor: Although the strategy was busted by units such as Apollo, Blitz, The Oracle ... still very useful in certain Epic Bosses that require a lot of healing.

Cannon Walker: Your ability to cause damage based on the number of enemy structures, cause with each new training improved gain more attention. In fact, the developer nerfed this unit because it was overpowered.

Shell Stalker: Like its WC cousin, the Cannon Walker, but applied to enemy armored units, this unit gains strength over time.

Ascaris: One of the stars at the time ... And even useful, especially against some Epic Bosses such as Black Lithid, Behemoth or Sentinel, against which it can control one of its Bloodthirsty units with great efects.

Assembly Plant: These structures never be outdated, given its capacity to build an armored unit, among which are many of the most powerful in the game.

And so, some other units shall be more fortunate than most of the others that, in return, are now in every respect useless and doomed to oblivion.
