Raynor’s team are delivered to the map in a dropship – a handful of Firebats (flamethrower wielding, short range heavies) and the more generic marines make up your initial force. The map itself is little more than a colony and a port connected by a winding, S-shaped road, and the objective is equally basic: escort a van as it carries 50 colonists to the port in five trips. The Zerg have wonderful timing here, with each wave of attacks becoming consistently more vicious until they’re dropping in from the sky right next to your tin of defenceless civilians.
There are frustrations to be found – the van cannot be ordered to stop and cannot be told when to leave, and if you begin to flag in one wave, you’ll be hard-pressed to prepare for the next. The challenge mounts regardless of whether or not you’re rising to it, while few concessions are made to strategy-blind morons like ourselves - there are no quicksaves or checkpoints.
