The Ani had LBX10s, and was an incredibly crunchy infighter. The only real tactics are to rush it or wait for it to run out of ammo, both of which almost guarantee you're gonna get mauled in the process.
And that's what I like about it. I was afraid to engage other 'mechs because I knew they could hit back at least as hard as I could hit them. In MW4, I remember the mission where I took on two Zeus (80t) and a pair of Thanatos (75t) straight away, then a pair of Fafnir (100t) followed by four more Zeus and a quartet of Longbows (85t).
That's 1,170 tons of hostiles - and I never felt truly threatened. That first Ani terrified me, though, especially since the first time I saw it it flattened Epona's Bushwacker with it's opening salvo.
