P.O.W. Rescue (unlocked at Level 05) is a new game mode introduced in Metal Slug Attack. The player is tasked with completing a set of 10 stages of increasing difficulty in order to get Unit Parts and Items, as well as Gold Bars (occasionally referred to as Gold Bullions), this mode's exclusive currency to spend at the local shop. Rewards drop randomly, with the exception of Gold Bars which drop after every stage with an even number.
The quirk of P.O.W. Rescue is that one gets 15 minutes total (of combat time) to complete all stages, and can retry stages as many times as necessary in order to reduce the time spent or score a win altogether. In the case of having reached the end of the path or running out of time, the player needs to "Restart" (which they can once a day; Restart refreshes at 0400 hours server time). In fact, restarting can be done voluntarily at any point, for example if the player encounters a deck they cannot beat.
Doing so, they are given a choice between "Normal" and "Hard" as a risk-reward mechanic - better rewards for more difficult opponents.
Having completed a stage on Normal difficulty, the player receives a random loot drop (aside from Gold Bars): the first drop is guaranteed and there is approximately a 40% chance that the second drop will take place.
Unit parts drop only after clearing Stages 3, 7, and 10.
As with other Shops, merchandise selection is randomised and refreshes 3 times a day at 1200 hours, 1800 hours, and 2100 hours based on server time. In exchange for Gold Bars players can get:
- x5 Unit Parts ( Regular Army) - 500.
- x1 Items (Silver) - 200.
- x1 Items (Gold) - 1,000.
- x1 Items (Platinum) - 10,000.
Current stock can be refreshed immediately for 30.
