One thing I personally enjoy in games is some sort of interaction with surroundings that actually affect things....
For instance, say there were to be a city world ar even a city on a planet, just simple barriers, drawbridges, pathways, doorways and more that could be activated by switches would make quite a difference....
Control rooms with security cams etc that could then be contested for control of the pathways through the city etc to allow your party through while attempting to block access for other teams...
Various items could be on delays that would allow time for others to take control, re-spawning gun turrets on delayed respawn, land mines etc
Imagine, for instance: (Similar to beacon mission) You have succesfully infiltrated the enemy base, one person mans the control room, the rest of the team are in strategic points in the maze....the countdown starts, and the first wave of robots are released....01's-05's mown down with ease...then troopers and warriors, on and on seg's warlocks....closing gates and bridges when members die, routing them to different zones, sending reinforcements to different areas....or then again, a fully PvP alternative.
New cybernetic implants lootable from robot planet that could provide extra features like extended jumps/limited flying, short duration energy or matter shields (why not throw in some new mindforce implants for these as well) ...add radiation damage + defenses against them..(Mmmm...Nukes...Nuke launcher/personal cannon!)., Camoflauge, Displace, Clone Image, Clone image w/decoy, Partial invisibility (Blinking), Invisibility, SENSE invisibility

, HP boost, regen, TEAM HEAL!!!!
(off topic alert)
Man, ive been a Cleric since the first dice and paper days....need more buffing stuff....Cmon
MA, you could make tons!!! Team Buffs? Low level team buff for instance....5HP team boost, up to 4 team members...seperate chip, 10pt damage from said dmg type absorbed or higher buff, reflected....
Say...(L) MF chip, 20HP buff for team up to 8, 8D (or whatever) Plating protection, 50% dmg reflected, Run speed increased, and health regen....damn that would probably be worth alot. And its been done. many times. elsewhere. Ive worked in IT for many years though, and can truly appreciate what a nightmare this might be to implement hehe so uber gratz in advance if this ever gets released
Whole new uses for mindforce, loads more chips...and pls....ember focus chip that allows you to tp while being hit?
One more thing while im at it PLS PLS PLS PLS let there be a use for filters and dampers soon.
Minigames in the bars that cost a ped to play lol
Sry all, woke up early and couldnt sleep hehe, had mad dreams so unloading here ;~}
