Some ideas to develop (alreayd present in the universe) :

- New characters to develop:
 * Geth primes (engineer with high armor, slow movement, long shot range, geth turret, combat drone and a bonus for other geth in the area to complie with the lore)
 * Turian female (for the pleasure of fans)
 * Turian Cabalist (biotics unit such as in the lore)
 * Vorcha with new skins (such as omega DLC)
 * Spectres : lot of possibilities for salaraian/asari/turian (they can be lots of differents classes)
 * C-Sec officers : they hire the finnest poeple of the galaxy why not put them at good use ? it can be soldier/engineer/infiltrator/sentinel and for the races :human/salarian/asari/turian
 * Mercenaries : they are present in the war efforts, why not in MP ? This could open a lot of viloent possilities with three differents factions (blue suns/Blood Pack/Eclipse). It offer a wide variety of troups and race (BS: Human/batarian/turian BP: krogan/vorcha Ecl: salarian/asari/human)
 * Talon mercenaries: why not but not crazy about the idea
 * Salarian STG : OMG we need more salarian, we all want a violent tazzik soldier :)

- New ennemies
 * Mechs army controlled by indoctrinated ? Why not we can have YMYR, FENRIS, LOKI, OGRE and rampart mechs (+ drones, ...) It is a wide range of possibility. But we need something to introduce them in the lore in SP such as a ANN report or something like that (we also need that for the collectors, the lore in SP should say that there is some collectors still alive making particular missions).
 * pirates/mercenaries : why not a band struggling for his survival or indoctrinated band.

- new objectives
 * a boss to kill at the end of the waves (in place of extraction: it is one of another) : geth armature/reaper harvester/A-61 Gun ship for Cerberus/idea for collectors ?
 * Planting a bomb (for wave 3/6/10): Package from LZ to objective and then time to instal the bomb (mix between others objectives)

- power and weapons already present in SP
 * the groundside resistant pack
 * other weapons not yet available
 * New heavy weapons (not always the same one shoter)
 * powers such as : flare/slam/dominate/...

- new combat mechanisms
 * New types of dammage : Acid/poison (such as in ME1) with DOT (dammage on time)
 * New related powers : acid grenade/acid rounds/acid powers/...
 * New related power combos : acid splash (such as fire explosion), the splash will, for example, make dammage in a zone and give a DOT to other ennemies

- and dreams :
 * open warfare : lots of ennemies/lots of allies on big maps
 * Objectives maps : suc as N7 missions but in cooperation
