Marine and Alien upgrades ideas

wikisam

My idea
1)Marine weapon and armor change look when upgraded
2)weapon tree :
-Commander weapon upgrading is giving points to the players
-Players has to spent their points in the weapon tree (like skill point in rpg games)
-this will make the player to research and choose the weapon they want and each destination give a different super weapon
-by getting killed or killing enemies you will get points that will be used in other skill tree (maybe defence tree ex: bullets that make enemy slow or bullet that
burns, carrying extra medpack)
-It will cost a lot of resources to reset the tree
-hot keys for weapon tree for fast playing

3)alien upgrading system
-Keeping the same ns1 style giving player too choose alien upgrades like clocking adrelalien etc
-commander has to upgrade each level to unlock the abilities from the upgrade tree (1 upgrade unlock 2 or 3 abilities)
-alien gameplay is damage, stealth and speed so upgrades tree should be focus in those things

plis comment and add more ideas thx
