Last night i has a idea about what to do after lvl 21:
SISTEM OF LEVELING GUNS AND CRITERS
CRITERS
1.- If you kill a critter certain number of times you will get a bonus against him
2.- this is like a sistem of lvls more kills more lvls more advantages
3.- advantages are little, for not kill the actual sistem
4.- is a way to grew up REALISTIC
5.- the advantages will be gived as Perks, with all his parafernalia, funny image, name and silly description.
6.- only work in PvE
Example
Mantis
kills lvl advantage
10 1 none
50 2 manti have -5% probabiilities of hit you
100 3 you have +5% of cause a critical hit in a manti
200 4 you receive -5% of damage from manti
400 5 you cause +1 points of damage against the enemy (per bullet)
800 6 you ignore all the DT of manti
1000 7 you cause +10% of damage to manti, and Bloody Mess is enabled against them (for funny)
WEAPONS
probably the most important part, you can lvl up you hability with any weapon
1.- Every time you kill something with certain weapon the xp also go to the lvl of weapon
2.- advantages are give as perks, again with all parafernalia
3.- the advantages are only for the weapon lvled up
4.- every weapon has his only scale of lvls
example
Weapon SMG 10mm (H&K MP9)
lvl xp needed perk advantage
1 1000 H&K MP9 Beginer none
2 3000 H&K MP9 First Step you get a bonus of 5% xp for normal lvling
3 5000 H&K MP9 No Fail you have -10% probabilities of have a critical failure
4 10000 H&K MP9 Degeneration your weapon degenerates 10% slower
5 20000 H&K MP9 Resistance you ignore 5% of damage resistance from the enemy PvE
6 30000 H&K MP9 DT YOu ignore 1dt from the enemy
and then,
as smg 10mm is a burster weapon you will have advantages with bursts. more damage per bullet for pve, and then for pvp, at las lvl you will need like 300000 xp for "you cause +1 damage per bullet in pvp"
this way old character will have a advantage against new lvl21 characters, and is a good way to especialize in some weapons and enemies
i know: is hard to implement but i cant
this
sorry for my syntax, im doing the best i can
