Metal Slug Defense

* In every level, your first move should always be to spend 40 points to upgrade
Action Point generation. Follow this by launching the cheapest soldier into
* You must collect Action Points to produce troops. The quickest way to create
AP is to repeatedly tap the lower left icon of Rumi Aikawa.
* You can increase your Action Points by freeing P.O.W.s. When a level starts,
tap the P.O.W. icon at the bottom right to learn what P.O.W. unit you are
rescuing. Use that to decide which unit to select for the mission. Each area
has four stages that have certain conditions for rescuing a P.O.W.s. You will
need to repeat stages with different unit combinations to complete it quickly
in order to rescue the P.O.W.s. Rescuing the second P.O.W. in a stage will be
more difficult, as the game knows the limits of your unit allocation. You will
need to use a combination of your available units to rescue the second P.O.W.
* Replay levels until all prisoners are freed to earn various bonuses.
There are three ways to earn medals (in-app purchase, winning WiFi VS ranked
matches, and daily logins). The daily reward is not always a medal, thus the most
reliable way to earn medals is through defeating opponents in WiFi VS ranked matches.
Selecting a higher level of difficulty will increase your reward. To do this reliable,
select opponents that have similar troops in their deck. Facing against an opponent
that has a deck that is significantly more powerful will be pointless. Medals can be
spent at the shop for specialized units, Metal Slug Points, and items such as Radar
to help free POWs.
Tap the "Customize" option at the main menu to upgrade your troops and base. This
is very useful for multiplayer mode. Max out all your troops first because they
are used often, but do not ignore troop production.
