Hostile Actions: Armoured Onslaught Supplement

Field Report: GRF Outpost Theta-9 – Audio Log Excerpt

“The dropships hit atmosphere at 0430. Four of them. No warning, no comms — just burn trails and thunder. We scrambled every vehicle we had, but it wasn’t enough. Not against them.”

“We fell back to the outpost to make a last stand… they had us hemmed in”

“Then came the Mechs. Big ones. Heavily armed, marching straight for our lines. The first shot took out the turret emplacement. The second buried the command post in flame. By the time we realised what we were dealing with, it was already too late.”

“This isn’t a skirmish. This is an onslaught.”

“They weren’t sending troops to fight a battle — they were sending machines to end one.”


The war escalates. The battlefield evolves. Are you ready?

Armoured Onslaught is the first full-scale expansion for Hostile Actions – Warriors Clash Under Alien Suns, the sci-fi miniature wargame of tactical decision-making, cinematic action, and narrative-rich warfare.

This supplement unleashes new layers of strategy, units, and destruction onto your tabletop — transforming every battle into a far more deadly affair.
