Great series, and Im glad we see a Sentinel return after all these years. Marine is great for army building, the grunt has a great purple, The green recon was another one of my favorites, not oly for the new weapon mold, but it turns out nice in person, Also the infected spartan is good to get alot of infected plasma swords. Last But not least, the Ultra Rare AC jackle. I was lucky to get 1, but the blue on the visor makes it look way better. Overall if you can find the series, try collect them all!
