My ideas

<div class="IPBDescription">for a good NS2</div>It’s just my ideas - u don’t have to like em and sorry for bad English and else I hope the developers of NS2 can use it to something or use it to get even better ideas.

Marine :

Give the Commander a menu where he can easy assign all soldiers to a squad and give all squads a mission easy and promote a marine to Squad Leader, so all squads have a squad leader.
And let the squad leader have a banner so all can see who and where he is and all soldiers in his squad gain more firepower if going whit him or stay Near him.
“it force players to work together and follow orders”
And give the squad leader the ability to give orders to “his” squad only, like :
fall back or cover me - All Attack. Stuff like what.
Talk to squad only chat.
The marine can see the names of all in his squad, so when he gets the order : squad go to waypoint!
he knows, who else is coming.
Let the Commander or squad leader change banner ability from guard/run/attack mode.

A new form for turrets :
More costly, but like a guard robot who can patrol a little area or the Commander can set it to follow a group of marines going to a waypoint.
And marines can weld it to full life again.

The Commander can research more stuff, like implants who give more run speed or cloak or firepower to the space marine for 10 sec and can be used only 1 time and first again when the marine die and respawn.
Other research :
Research New weapon types like a sonic pulse rifle or a energy canon or a flamethrower for vent cleaning.

All marine gets a refuel implant that can be changed to life or armor and only can be used 10 sec after he last fired a weapon or did take damage and the implant will slowly regenerate again, so the marine can use it more times.

Alien:

Alien Commander can change overall mode for his life forms, from like more life and protection mode to full rage mode. A faster run Speed/Get res faster Mode, but whit lower protection/dmg.

A better minimap for aliens, so a alien can request help or show something on the minimap to all other aliens whit color pings on the minimap, where a green ping mean “many soldiers INC” or a red ping mean “need more to a ambush” and white ping mean “need help”, something to improve alien teamwork. More alien talk sounds, but whit low sound so any marine nearby can’t hear it.

Instant upgrade to a ability like speed or focus, it really suck if the hive is under siege and a skulk have to wait for his upgrade to finish, die 2 sec after and now have to wait for respawn + all upgrades again.

A new or 2 new chamber types for alien, so we don’t always get the combo MC/DC or MC/SC.
But can get many combo’s. It’s a hard one

A least 2 new types of aliens : a 100 res life form “a Tyrannosaurus rex” and something to 20 res who can slow down marines or dmg all in a area or mass parasit all in a area, a “alien mine layer” life form who is good vs groups of marines.
