k let me try to clarify the great/cheap thing the unblockable is
if you notice sometimes when you do the mouth laser(mouth laser will be referred to as spit from this point on) it hits twice for no apparent reason. This is random.
the unblockable can be setup severals way but the best way to set up the unblockable is after you kill a character with sent.
As the character is coming in, you dash as close as you can to them, but stay outside their range so that they cannot hit you. Then you do a ducking spit (down and fierce punch). you do it way early, so that the bulk of the laser misses the character but the very last bit touches the character as they are coming in, and it hits the character in two direction simultaneously( up and down if i remember correctly). either way the laser becomes unblockable.
the easiest character to do the unblockable on that you will usually see in gameplay is psylocke. Closely followed by magnus. The unblockable is free on these two since they can’t get out. the unblockable is hardest on sent. Cause his sprite is so big.
Cable- never do the unblockable on cable unless he has no bars, or you know for sure that the person you are playing does not know how to get out. (to get out cable can just come in with fierce punch and then super you for free). that’s why cable is da man.
ways to practice the unblockable. The unblockable is a skill you need to master. I have won entire matches because of that shit. Best way to practice is to have a friend sit there with you and you snap him out with sent and then you try it. You cannot put the computer in all guard mode, cause the computer will cheat and block both sides.
that’s why the unblockable is so hard to get good at.
there are also several other setups you can use during gameplay, but that is another topic.
Hope this helps.
