Free Geek PCs have serious reliability problems IME. My son went through their program as part of his Senior Project, and I went along for fun -- we both got refurbished Linux machines at the end and neither one lasted more than 6 months before failing. The recycling part of their process is great for the environment though.
Broadside with HRR and SMS, plus Target Lock comes in at 131 points. Give it a Seeker missile or drone support and you're right under your 142 ceiling.
Crikey. Coldstar suit now has 4 fully customizable hardpoints. 4 Fusion Blasters, 40" move, no penalty. Hit on twos, with even a tiny bit of effort re-roll ones. That'll leave a mark on anything.
I've been using Firesight Marksmen for a while now, and they're superfantastic. A couple of them interspersed with a few Fireblades, and your markerlight woes disappear.
Beautiful model, really well done. When I first saw the promo pics, I thought it was the weirdest damned thing ever... but after seeing yours I'm a fan.
