I want a simple tactics game based around the idea of space stations.
Levels would be randomly generated with various functional parts of the station grouped, some "rooms" could be found in various places and sometimes the groups merge together- a medbay might have been generated with a garden, and had the Kitchen latch to that, forming a full fresh-as-it-gets bar and grill and ER.
You would be sent with different missions, determining the amount of damage the station has taken before you arrive and the population as well as their alert level. If you're coming as a primary invasion force, the station will be well populated and the people in the station will be more or less ready for you, whereas if you're salvaging, the station will be little more than space junk and, at best, contain a few refugees, or at worst, an alien hive.
You get infinite units, but you can only send a set number of waves and each vehicle can only carry so many units. Unit generation is more or less balanced so that you don't wind up with one guy completely maxed in stats and one guy who will immediately trip over the air and break every bone in his body in the fall and die before he hits the ground. You can set stats to blind so you aren't completely sure what the stats are.
Let's say you have to take down a station. Your first wave is a WHAL9K Carrier, with a total of 6 crew space.
The "Whale" Carrier is a mid-sized ship, what do you mean it only holds six crew!?
Four Soldiers = 1 Crew Space.
This means you could send a force of all footsoldiers and have 24 units on the first wave. This isn't smart.
Two Hardsuits = 1 Crew Space
Hardsuits are soliders in cool mecha bodies. They get all the cool weapons, all the awesome abilities, and all the hot babes. They are varied, but they are linked in that EMPs will completely wreck them for a few turns. This is bad when you breach a door with one, watch it get hit in the face with an EMP, and then sit there, blocking the door, getting made into swiss cheese by enemy weapons. Used right, they're menacing.
One Mecha = 1 Crew Space
Mecha are soldiers in badass mecha frames. They sit in a cockpit rather than move inside a suit, and have unparallelled "fuck shit up" abilities. Sometimes walls get in your way. Use a Soldier with an item, using up the item and using a whole turn, to break a wall, equip a Breaching device to a hardsuit, still requiring a turn but not using up items, or just break the fucking wall with brute force, immediately breaking the wall and scaring the shit out of anything behind it.
Plus, they have the best weapons. Period. Most are ineffective at damaging ground units, but there are some designed to slaughter, such as a mounted LMG. There are also weapons such as flashbang mortars to assist in soldier-killing.
Different units have different strengths and weaknesses. Some soldiers are fantastic at killing other crew, some are experts at killing people encased in a hardsuit, and some are mecha-slaughtering demolitions masters. Hardsuits can be equipped to deal with fleshy hordes of soldiers, built from the ground up to stop others like it, or be designed to replicate Mechanical David Vs Goliath. Mecha can be murdermechs, mechamidget stompers, or the most badass rockem-sockem robots you've ever seen.
Say on that mission I take two mecha, four hardsuits, and eight soldiers. One mecha is for anti-mecha, one is for anti-soldier. The hardsuits are made to counter other hardsuits, and the soldiers are varied as to what they can kill, 3 for hardsuits, 3 for mecha, and 2 for other soldiers.
I get two later waves, each a single Shooting Star carrier with 2 crew slots each. These carriers are fun in that they crash into the station heading for a beacon placed by other soldiers.
The enemy force seems mostly unprepared, as few trained security members are backing up a force of regular employees, as well as three or four hardsuits. My squad was built to counter Hardsuits rather heavily, and the two Hardsuits assisted by the soldiers takes them down, I lose only two anti-HS soldiers in the process. I was not, however, built to counter the fucktons of fleshy soldier they have, and once the hardsuits go down I eat facefuls of EMP and the tide starts shifting. All is hinging on my anti-soldier Mech which is steadily taking damage, and I know they're rallying more defenses deeper in the station. Still a minute before the first Shooting Star, so I place the beacon in a corner near a window out to space and retreat. They don't see, or seem to care about the beacon, but I lose my first mecha trying to hold them off. On that first Shooting Star I have two anti-Soldier mecha inbound.
This causes the battle to turn as soon as the lander crashes through the window, killing a good amount of enemies in hiding and unleashing chaos. They retreat VERY quickly, allowing me to push forward.
As soon as I reach new territory, two new mecha burst free from a wall, revealing that I've come very close to their medical center. First, I must defeat these two mecha- my anti-mecha immediately engages but it seems that they're a very close match, as the other of their Mecha unleashes fire on my two anti-soldier mecha. I fight back ineffectually, managing to hold my ground but taking heavy losses everywhere. I'm down to a hardsuit, four Soldiers and a very damaged mecha. The next Shooting Star is ready, and I lament the fact that it is a one-way craft as I call for four hardsuits, one for each counter plus another anti-mecha unit.
Again the tide turns in my favor, as the Medbay is evacuated and the shipboard AI begins evacuation protocol. Smashing through medbay reveals the Robotics lab, allowing me to stop some hardsuits before they deploy, and leaving me winning with four soldiers and five hardsuits. I push more, and reveal Security.
Security was bracing for me the whole time. As soon as the wall is breached a hail of fire opens up, forcing me away from the door I just made. The firing fizzles as soon as a clanking noise is heard...
EMP grenade. All of my hardsuits are disabled for a turn, as Sec members pour out and kill my last remaining soldiers before using hacking kits to open the hardsuits, killing the pilots.
I caused massive damage to the station and all crew will have to evacuate, but I also gave them five hardsuits loaded with our intel and tech. Mission very, very unsuccessful.
