Brainstorming phase - Amoeba Shooter

I was thinking of a simple game I may be able to do on my own, that I feel I would like to play, and this is what I came up with, just looking for some comments and criticisms at this time (as I haven't learned enough Torque yet to even make a proper prototype). Remember nothing is set in stone at this point

Amoeba Shooter
-Fairly standard multiplayer-only(possibly single-player with bots) FPS game
-Aimed at people who enjoy playing frantic FPS games for fun(not too serious)
-Eliminate all forms of pickups
-Eliminate ammo management

-Only one gun with 2 shooting modes
-First shooting mode is similar to the Quake 2 blaster, but with a bit faster moving shots, and being
able to shoot a bit more frequently
-Second shooting mode is like a rocket launcher that lets off a large blast radius
-Strength of the guns could be around 2 direct shots to kill with the rockets, and around 7 to kill
in blaster mode(will be changed and balanced through much play testing)
-The firing mode will be shown by having the model of the gun open or closed(similar to Samus' arm
for normal firing/rockets in Metroid Prime Hunters), as well as an icon in the bottom right corner
-There will also be a spike on the side of the gun which can be used as a melee weapon which will
score an instant kill(or just be crippling, again this is for playtesting to decide)
-Health can be regenerated by standing still and not firing(at a rate to be decided) to eliminate the
need to search for health packs
-The GUI should only consist of an event log/chat log(top left), health bar(bottom left), and firing
mode icon(bottom right) (all subject to change of course)

The gimmick(where the amoeba name comes from):
-The game is a team deathmatch game, but not in the red vs blue sense, it starts off with everyone
being the leader of their own team
-When a player is killed they become a part of the team who killed them
-When a team leader is killed their team becomes part of the team of the player who killed them
-The game goes on until every player is on the same team
-Suicides and accidental deaths make the player become part of the team of the closest living player
at the time of their death(team leader rule applies here as well)

Scoring:
- Player is declared the winner if everyone is on the team they're the leader of
- When a player scores a kill, the current members of his team all get a point
