Qvova got there first, running straight through the door without slowing. Glass burst everywhere. A second later he was firing.
‘Multiple enemy ahead,’ he voxed. ‘Engaging.’ His brothers were at his side a moment later. Hyper-velocity flechettes shrieked into the hall. A civilian went down, his body pierced through in a dozen places. The civilians began screaming again. Agapito put himself between the darts and the people. A number hit him, pinging into his armour and sticking fast into the plating. Before he reached the door his left side was thickly quilled with needles. Beyond the doors dozens of Aphelion-2’s defence forces were arrayed in another large room, this one a long rectangle, three storeys high, with a gallery around all sides. Pieces of abstract sculpture floated at the gallery level, equidistant from one another. One wall was a single, huge run of glass overlooking the ocean. They were close to the centre, but now opposed.
As in the previous chamber, there was seating, this time arranged in high-walled booths that the enemy were using as cover.
Agapito plugged the gap between Qvova and Kway. Flechettes tinged into his armour, burying half their ten-centimetre length in his battleplate. Muted alarms alerted him to damage to the suit’s fibre bundles. Lubrication fluid seeped from a dozen holes. Ferrofoam sealant bubbled around more, closing the breaches. None of the darts penetrated all the way through to his undersuit.
…
We will kill them all, then. These guns cannot get through our armour,’ said Kway.
