You can still install custom ROMs, I'm running one right now. They make you wait a week to unlock the bootloader, however it seems there's a possibility of that going away in the future, it's not very clear.
But also, seeing as the phone is using a mediatek chip, your custom ROM support will be limited.

Checks out.
Last year I made a fake twitter account using a temp email just to look at some tweets from an artist's account. The fake account had a random gibberish username, and I only used it for a few minutes and logged out. Then, about 6 months later I needed to use it again to check something, so I logged back in and noticed the fake account now had 200 followers.
Draw your own conclusions from that.
I was just about to answer OP with "any ut99 weapon". Even the backup melee one was great in the right situation.
Though my favourite of them is probably the rocket launcher, but only by a thin margin. Mostly because my favourite map was always the small dojo one (morbias][), and that only has rockets and the occasional redeemer. Just pure death match all the time..
