As a regular player of tom Clancy game I have been storming up Ideas so the game live on I would like to see a mode where 4 players or yourself go's up against enemies from in game in a wave based mode and every 10 modes they go up against a boss from campaign like el muro or la plaga and if you survive 50 rounds you vs the predetor giving u supply crates and weapon and vehicles
That would be too contrived and repetitious for my tastes. I've had good fun implementing a sort of survival mode by just not using the HUD or Skill Upgrades, and playing on Extreme. It's very much like a Survival Horror game, except the horror is just feeling like your stuck behind enemy lines with much less resources at your disposal.
