Needs more work.
Real guns, as aways ignore lawyers etc. Disregard cowardly countries that use freedom as a brand to sell, name for torture camps etc, ironic for them, use designs the cowards copied from. Functional originals.
Longer sight range for enemies.
More enemies.
OpenGL, linux.
Low resolution support and engine scaling using nearest neighbour. Menus and GUI set to custom resolution too, 480x270 for both anyway. Make elements readable at that res.
Make realistic cut to slap dev team from dependence to former director. Cut out the animu, all the shit weaboos would approve of. Salanthropos becomes a bipedal weapons platform instead. Quiet is good at being quiet etc. Skip all the scifi bullshit, also unfuck the previous games in the same fashion for rereleases using similar gameplay (controls), cut out most of the conversations, where they are saying something like a parody or reapropriation. No mention of countries or country affiliated organisations. Fuck all those pathetic parasites.
Redo engine for realism. More texture for faces and terrain. Use tesselation for building chips and close terrain, ground. Physx/Havok for explosions, wind, bullets, bullets bounce off rock. Oscelot as buddy makes use of this.
Low resolution blends lack of detail. Use post process effects to make even a simple corridor full of visual appeal. No texture filtering, affine mapping, Framerate, texturing and level of geometry demonstrating quality.
Weapons accurate but require player to control them eg move second stick down when firing.
No AA(!)/Increase AA into the distance/TAA.
Use interlacing, line stays, new line replaces old one. No bobbing. Free motion blur that eliminates stuttering. Include deinterlacing options for idiots.
Low and detail and poly should look passable on low res. increase anount of action and health. Like the video demonstrating the difference between GTA4 and 5 player and enemies harder to kill. Body armour, use speed when used to combat or to play realistically, dead then if not acting fast.
More costumes, cutscenes aren't, remain as playable gameplay, witness impressive things by seeing them looking for them and helping them, whole game not knowing when something good is happening, all seeming story related.
Controls:
R1- Cqc/grab/action, fire
R2- Aim and zoom strengh, full press for secondary fire
L1- Hold to sprint, press to roll (roll when jumping to 180turn, done fast enough turns without jumping)
L2 - Crouch height, fast all the way down to jump, moving from full press while jumping crouches in midair, press it when landing with forward motion to roll and save leg/back damage if pulling back on stick or opposite dirction of movement then crouching when landing stopping forward movement, press crouch when landing with no stick movement to land silently, time press and speed to carry on speed of fall when landing, all the way down to roll.
Endless waves of enemies and large numbers, well equipped. In urban areas them spawning where not checking or behind after a period of time.
