Happy to see a true update to XCOM in the works. Got my pre-order in and looking over the FAQ when I noticed that there would be no fusion launchers or human psionics in Xenonauts.
I have to say that this made me a little sad. While I never really got into psionics in the original XCOM, I had a blast (yuk, yuk) shooting those rockets around corners and up and down elevator shafts.
Less toys to play with will always feel like less. I hope that these and more may one day make their own appearances in Xenonauts, either by DLC or by mod community.
