dk how but I have total dementia of where I played it, what it was called and kind of vividly remember only a single part of it as it really grinded my gears as a kid. it is a 2D flash game which was based in space or Earth with braindead swarms which you had to shoot. the game mostly took place in metallic bunker type areas. it also had a story element to it and I think the characters spoke with textboxes and had their artwork was displayed at either the right or left side depending on whether it was the player character or a NPC. the player character and a few (if not all) wore a kind of armor akin to the Halo spartans but in 2D. there were 2 installments of the game, the second one had the same name w just a 2 appended to it. I love both games dealy but only finished the 1st. my memory is from the 2nd game.

from my recollection the lvl goes like this, the player character is with a female NPC from the same faction inside of an enclosed room inside of a bunker. she is dressed in a similar armor as the main character but w/o a helmet. in prior lvls or the same one she has a gun, which she uses to assist the player in thinning out the enemies. she has a father that has a higher station than both characters. btw she and the main character were kinda a thing. together both the characters plan to escape but their path is blocked a hoarde of enemies that they have to mow down. the objective is to advance through the hoarde and make sure the girl does not die. in my playthrough she died. a lot. when downed she has a health bar that depleates with time or from enemy attacks. idr if there existed a revive mechanic and if it did I was never able to figure it out.

partially restored another memory of a lvl whilst writing. the lvl was a maze with doors. you'd enter through one door and then would be faced with a few more doors. from which you had to find a route to the exit. I do not remember if its a level from the first or the second game, but I think the same NPC was a part of the level and this lvl was the one prior to the one I mentioned above. I am not certain abt this tho.

it has been more than a decade since I last played this game and I've been searching for it ever since. if by sm miracle any1 is able to solve this... I will be forever indebted and grateful. you will be helping a grown man connect with his past and enjoy the joys of his childhood once more. thank you!
