15 Minutes

15 Minutes is the thirty-third level in Metal Arms. Following Glitch's capture in the aftermath of the second Droid Town invasion, he is sent into the Mil Colosseum, where he is forced to engage in battles for the Mils' entertainment. There is one Secret Chip in this level.

Trivia
• Glitch's Battery bar is reduced to three in this level and all his weapons have been confiscated. This reduction and limit of arms remain in place until the Mil Colosseum part of the story is passed.

• The battered, elderly prisoner in Glitch's cell reuses the generic Droid seen throughout the game, but lacking his backback and missing a right hand, with wires sticking out of his joint.

• The battered, elderly Droid has a pair of Cleaners on him that can only be obtained by his demise. This can either occur by Glitch directly eliminating him or by prompting the Grunts to destroy him (by forcing him out of the cell).

• Despite the means of which cause the Droid's demise, Glitch is in some way responsible for his destruction at the time, which actually places Glitch's morality to question. However, it could be seen as a mercy, depending on what events might've occurred later to torment the droid.

• Glitch is provided with six optional weapons to use in the Colosseum battle, but may only use one. This is important for Secret Chip collectors, as the Chip is located in a propelled unit hovering above the arena. Should Glitch choose the Ripper (it's a level 3), the weapon lacks the means to bring down the unit, thus it becomes impossible to acquire the Chip.

• This is the only time a decision Glitch makes beforehand matters at a later point in a level.

• The Grunts serving as guards are completely immune to damage and their limbs cannot be destroyed, thus forcing Glitch to obey their demands. They do, however, have shields that can be worn out, but they don't have any impact on the Grunts' vitality.

• If Glitch keeps attacking them, the Grunts will retaliate (usually after their shields are gone). Because they cannot be destroyed, Glitch will be unable to win and survive, should he stand his ground.

• The four Mining Laser Grunts located down the tunnel to the arena can be provoked if attacked and might actually fall down to where Glitch is. Unlike the guards, this Grunts can be destroyed.
