Not because you can, but because you know that you should.
Yeah I was put off by the 25 foot tall...Broodlord? Maybe the game will have a variety of sizes of genestealer and BL, its possible there are strains that have consumed ogryn or other large species and have bulked up substantially.I was thinking about it and I'm not sure facing only genestealers really makes for a complete shooter in 2014.
The only thing that could give it some variance if it was a true space hulk. I.e. literally a load of ships crunched together, so Eldar, Ork etc. Otherwise there will be young genestealer, teenage genestealer, old genestealer, broodlord.I remember old Star Trek away team which had that nice bent, whereby it was alien ship 1, 2, 3.
