I don't know the "Team Fortress style gameplay", so can you explain it a bit more?
Team Fortress is a game where players have to choose from 9 different classes. Each class has their own strengths and weaknesses, encouraging players to use teamwork. Each class also has their own set of weapons (or in this case markers).
I've made a list of the different classes bellow. I've used the stats from Team Fortress 2 because that is the Team Fortress game most people are familiar with.
ScoutRuns fast and can double jump (the kind where you jump then jump again in mid air, not the Quake 2 kind) but has low health.
In Team Fortress 2 he's equipped with a scattergun, a piston, and a baseball bat (for melee).
SoldierHas a lot of health but runs slightly slower than most classes. This is a very balanced class, making him great for beginners.
In Team Fortress 2 he's equipped with a Rocket Launcher, a shotgun, and a shovel (for melee).
PyroReally good for short range combat, but can't do much at medium and far range.
In Team Fortress 2 (s)he's equipped with a Flame Thrower (secondary fire blasts compressed air which knocks back enemies, redirects enemy projectiles, and extinguishes flames on teammates), a shotgun, and a fire axe (for melee).
Demolitions ManGreat at medium (and maybe far) range, but terrible at close range. He can lob projectiles from behind cover.
In Team Fortress 2 he's equipped with a grenade launcher, a stickybomb launcher, and an empty bottle (for melee).
Heavy Weapons GuyHas the most health, but runs the slowest. He's great for medium and close range, but can't do much at far range.
In Team Fortress 2 he's equipped with a minigun (secondary fire will wind up minigun so you can prepare to fire), a shotgun, and his own fists (for melee).
EngineerHis low health and weak weapons make him a terrible combat class, but he can build a sentry gun, dispenser, and teleporters to aid his team, making him a strictly defensive class.
In Team Fortress 2 he's equipped with a shotgun, a pistol, a wrench (for melee and upgrading, repairing, and speeding up the construction process for buildings), a construction PDA (to build buildings), and a destruction PDA (to destroy buildings. Although the player can right click buildings to carry them, it would be much better to destroy them if the player has to travel a large distance).
In Team Fortress 2, the sentry gun is a turret that will automatically aim and shoot at enemies as long as the sentry gun can draw a line of sight and the enemy is within range. The dispenser gives health, ammo, and metal (for Engineers only) to nearby teammates. And the teleporter takes teammates from the entrance to the exit. The Engineer uses metal to upgrade/repair buildings.
MedicAlthough his low health and weak weapons make him a terrible combat class, he can use his medi gun to heal teammates.
In Team Fortress 2 the medic is equipped with a syringe gun, a medi gun (for healing teammates and will build an uber charge when healing which will make teammates invincible for a brief amount of time), and a bonesaw (for melee).
SniperHe's great at far range (and maybe medium range) but terrible at close range. He also has a low amount of health.
In Team Fortress 2 he's equipped with a sniper rifle (can get head shots and will build a charge while the player is looking though the scope, making the shots stronger), an SMG, and a kukri (for melee).
SpyThe spy can disguise as enemies and teammates and can cloak, but being lit on fire will reveal his cover and he has a low amount of health.
In Team Fortress 2 he's equipped with a revolver, a knife (can get back-stabs which will instantly kill enemies), a disguise kit (for disguising), and an invisibility watch (for cloaking).
This sounds like a totally new mod. +neg vote
Just play TF2....
I'm pretty sure we could just add some models, but that's open for debate.
