alright so since this is going nowhere
AFTER 1 HOUR, 24 SLAUGHTERED RED-EYED BEASTS, A NICE CRUISE, AND A 3-COURSE DINNER:
You finally emerge from the dark forest and are on route to the swarm lobe you need to take out. It's important to avoid any kresh a-

A single kresh infantry appears seemingly from nowhere.

It stops in it's tracks, staring at you, blocking your path. You realize that the surprise aspect of the mission could have just been blown. This could result in your entire squad becoming dead, or even worse, infected.

You stare at it's large, cold, unforgiving eyes. Will it report what it is seeing? Will it endanger the mission, or will you kill it in time? Did it even see you, or is it just confused? There is no risks to take. You must destroy it, at all costs, without making a big scene.
So I present you with a choice, ENGAGE COMBAT or find a different way?
