Sweet! I'm still looking for the bigger mechs, but slowly filling out with heavies. Just today found my first Catapult since that story mission. I want a couple of those, then of course I'm searching out some Stalkers and Atlas.
The game has a good pace, keeping the mechs coming based on your missions and all, but I'm SICK of Shadowhawks, Vindicators and Panthers. Getting close to having the ship finished, but I'm resisting the 3rd bay just because I don't need it.
