By improvise, I mean find some health! Find some Weapon energy! Unless you're playing TLMS or LMS, in which case just change your weapon! The megabuster isn't half-bad for a starting weapon.
Of course getting health and weapon energy are options, but he said he would "teach people when to use items"...there isn't much to teach there, along with changing weapons.
The megabuster is pretty bad compared to other weapons. It isn't impossible to use properly, in fact I've done well with it many times before, but there are almost always better "replacements" on the map. You can use the metal blade, needle shooter, ice slasher etc etc etc

Also deciding whether or not to take a teleporter also isn't a strategy. Yeah sure someone might be camping it but in a free for all that's hard to do for too long as you are bound to get killed
