                                to look at us, but after the archive collapse 
                                we were hurting, especially Nem. We just needed 
                                to get back to the elevator and wait for some 
                                resources to trickle in, but they kept the pressure 
                                on, every step of the way. We put Nem in the middle, 
                                they attacked the middle; we put him in back, 
                                they attacked the back. It only took a few spikes 
                                to finish him off: a Lerk shattered a window and 
                                nailed him before we could cover. Hit-and-run 
                                bastards. Then they started stalkin' Hanover. 
                                I'm telling you: they knew who was hurtin', and 
                                they were picking us off, one at a time.&quot;</p>
                              <p><b>Thesis:</b> the most efficient ambush targets 
                                the weakest prey. Or: the best way to attack many 
                                foes is to reduce their number as quickly as possible. 
                                Injured humans release microscopic triggers when 
                                injured or harmed &#150; these aliens must be alert 
                                to these emissions, evolving skin receptors that 
                                can &quot;taste&quot; the air and pinpoint injured 
                                foes. TSA armor should suppress tell-tales like 
                                these &#150; the aliens must be amazingly sensitive. 
                                Or perhaps the ever-present bacterial network 
                                is responsible. This evolution is probably susceptible 
                                to all kinds of tricks, or evasions &#150; but our 
                                experiments with &quot;scent bombs&quot; proved 
                                disastrous. As is the case with all aspects of 
                                the Kharaa, we need more data &#133; but what 
                                is an acceptable number of deaths for each bit 
                                of information? For now, we must be satisfied 
                                with observation, and observation only.<br>
