are power kits worth the money? because it seems like a lot of reds being invested for a very small amount of additional damage

Not on weapons. On torso they are worth it. Personally I would buy a whole bunch of premium for more SM then power kits. 30 days of 2x SM. Personally I can get 700k SM per day. This equates to about 21000000 SM per month. 1 Million SM Equates to about 40k-80k Exp. Which is about .9 a Power Kit. Premium costs 250 tokens while two Power kits cost 180. (You can't buy a third since it cost 90 tokens)

ok, thanks for the advice

agree with tickle

but this depends with the level that you are fighting;
because most level one players upgrade their weapons and torsos so you need it too to give a good fight

in other levels you can play smart and win and
when you fully fuse ur torso ( it gives+75hp ) and it needs like 537 600 power; to reach it so players buy power kits

some players who can pay, have upgraded their weapons to +16 damage too

you know if you have extra +16 damage in a weapon like needle mark
it will produce like 100 more damage at the end all together ,so it depends on the usage, if you use a weapon a lot, upgrade it a bit

if you have like +6 - +8 in your weapon that's enough i am still using some weapons with only +5 extra damage he he
