An Idea for a Gamemode; Antlion Survival

[Jacos]

(If this has already been suggested, then this is my idea of what it should be like)

Players spawn in an open field map. They have to CONSTRUCT their own houses out of wood. Resources would spawn randomly around the map (Wood, bandages, bullets, weapons.)
Wood can be made into wooden props, for barricades, structures, or Wooden Spikes (If an antlion launches itself towards these and hits them, it is instantly killed)
Antlions have four ablilites;

-Attack (Only possible while on the ground.) (Left Click)
-Jump (Antlion launches itself into the air with its powerful legs. Only possible while on the ground.) (Right Click)
-Launch (Can't think of a good name) (Antlion launches itself forwards in mid-air, while holding it's front legs out. Causes damage to any player the antlion collides with and knocks both players down, and can possible destroy wooden walls or accidently kill the antlion. Only possible while the antlion is in the air.) (Left Click)
-Glide (The Antlion glides through the air, making it possible to travel very quickly, scout areas with humans in it, taunt humans, or glide towards where you want to launch yourself at.) (Right click)

The idea is that the humans must make a base (Out of wooden props), scavenge for items, and attempt to survive.

Classes;
Former Military: The player was once in the military. The player has +25% accuracy when using firearms, and can run 10% faster then other players. The Former Military starts with a pistol with only six bullets.
Doctor: The player was a doctor before the Antlion Wars, and can bandage players with +50% effeciency, and 10% faster. The Doctor starts with three bandages.
Former Combat Medic: This player was in the military as a field medic, and can apply bandages 50% faster, with 10% more effeciency. The Former Combat Medic starts with two bandages and a knife.
Scout: This player is a former military scout, and is quick - 40% faster running speed then normal players. The player also has a 10% accuracy bonus with pistols. The scout starts with a pistol with two shots.
Engineer: This player can construct wooden props from scavenged wood like all other classes, but receives TWO of the prop when he constructs it. The engineer is the only class which can construct wooden spikes. The engineer carries some fairly heavy equipment, making him 10% less fast. The engineer starts with ten wood, three metal and five nails.

Crafting & Scavenging:
Wood and Metal would spawn around the map (Aswell as other supplies.).
It could be crafted into the following items:
Three Wood = Table.
Two Wood = Small Table.
1 Metal = 4 Nails. (Used to keep objects attached to things, great for barricades!)
Four Wood and One Metal = Reinforced Table (Great for barricades!)
Twenty Wood + Five Metal = Reinforced Wall (Almost always kills antlions launching themselves at it.)
Ten Wood = Crate
Fifteen Wood + Three Metal = Reinforced Crate

Features (If it was made);
Antlions that could fly
Scavenging
Classes
Crafting
Teamwork Required
Could be popular on Fretta, if the Crafting System was gotten rid of and scavenging wood/metal was replaced by scavenging wooden props / nails.
It could possibly make a good gamemode for light roleplaying, if food, water, and varias items were added.

Please don't tell me that "I copied TF2 classes", I only realized that there were simularities AFTER I wrote down the classes. I didn't make them close to the TF2 charaters purposely.

So, what do you think about my idea for a gamemode?

I would be grateful for criticism.
