The thing that I hope most for actually isn't a game, but a game engine. I'd love to see any game made with a modern, refined incarnation of the Silent Storm engine, with real modern weapons and armor, a better armor system (Silent Storm Sentinels let you wear body armor, but that was it), including scavenging armor off of dead bodies (sometimes damaged, sometimes not depending on where they were hit with what), shotguns as well with all of their versatility (shells, slugs, non-lethal bags, Dragon's Breath incendiary), more ammo (including incendiary), melee attacks with ranged weapons (pistol whipping and hitting someone with the stock of a rifle, for example),specific unarmed attacks, including wrestling for control of items(maybe even pickpocketing),strangulation, or quick punches and kicks,the ability to mod weapons, including scopes, suppressors, ext. magazines, or even just decorating them, accurately shaped charges for all explosives, expensive drones that can be used to aid in missions, but are a serious investment, especially if destroyed.
For those not familiar with the Silent Storm engine:
•Combat takes place in a turn-based mode while missions will start in real time, meaning you can set up your soldiers and sneak around in real time.
•Every bullet shot has an effect on what it hits, even if that just means leaving a mark in the dirt. Bullet strength in the first game is exaggerated, with machine guns and rifles being able to tear down concrete walls. Ideally, this new engine would be much more realistic.
•Fully destructible enviroments. If you want to shoot a hole in a wooden floor and toss a grenade down you can.
•Soldiers actually point at where they shoot and the bullets do not travel on rails, they can bounce off of some materials.
•Actions are performed by expending Action Points or AP.
•Any enemy dropped items can be looted and used by your own troops in the expansion, they can be sold for money that can be used to buy other equipment and ammunition
•Up to 6 soldiers on a mission
•A range of different medical and engineering items with distinct uses
•An HP (Vitality Points/VP in-game) system hat includes extra symptoms caused by damage to specific areas (head/explosion damage may lead deafness, head damage may lead to blindness, legs being shot can make one immobile, the current weapon can be dropped if it or the arm is hit. Specific body parts can even be targeted to shoot.
•Different actions and weapons produce different amounts of noise and people can hear eachother to get a rough idea of where they are. They can also shoot blindly at the area (or just free aim) with a lesser chance of hitting. The AI, if suspicious, will capitilize on this.
Honestly, I don't see why nobody have used this engine for anything else, or even made a engine close to matching it. I'd love to see all tactical combat games return to this.
