Ive been thinking for a while I would love to see a sort of parallel series to the main numbered Halo games.
The idea I’ve had is for a 3rd person tactical shooter not too dissimilar from Rainbow 6 (but not 1st person), being serious, gritty (though not too gritty) and sometimes a bit frightening. It could involve the Innies vs the UNSC in an untold skirmish on one of the many colonised planets.
It would feel different from the Halo we know, yet all the guns and vehicles would exist in the states we know them, same sound and handling etc.
I could imagine the beginning of the game would have you be a normal civilian living his day to day life in a big city, possibly driving from point A to B slowly allowing you to take in this awesome futuristic place (maybe this guy could be on a hands free talking to a workmate or listening to the news that would give the player some hints of the horrors that are about to happen), then all of a sudden, a high rise building explodes in front of you, followed by multiple explosions and being thrown out of your vehicle from the shockwave.
You wake up shortly after, being dragged away to safety by some man in battle armour. The player will now become this man, maybe a marine or special forces type. More explosions in the distance sound, while seeing ODSTs drop in around the area from orbit. You as the player, or character for that matter have no idea who is behind these attacks, but it sure as hell doesnt look like the covenants doing.
Anyway ill stop there for now, yet I could see something like this running in parallel to Chiefs story and eventually linking up. This would also give players a chance to really get to know more about the Insurrectionists and see the Halo Universe in a different light. Humans vs Humans, In a place like the Londons and New Yorks of today, just 500 years in the future.
Would you guys like a spin off series in a more serious tone?
