Very Nice job!
I hope if u use some great 3d graphics, the game will be a great TPS(Third Person Shooter). I really love it, its much good.
Some suggetions:-
1) Turn off one thing, when the the soldier head, both legs, gets a shot then make it die, instead of leting the soldier run without a head. And can be alive without both legs.
2) Add a inventory to the Soldier so he can take about 3 weapons, Also give a knife to the soldier so that if he have no weapon he will use knife.
3) Your game need just some more hard work, and i hope this is a perfect game, u got a great idea. Try adding much quality 3d graphics.
4) Add another level (" Defend the flag "). so the soldier will defend the flag from the attack of the enemies. Give 100% energy to the flag. Reduce its energy 10% per shot.
....... No more suggetions, i hope the suggetions above are enough, and if ypu follow them it will help you make the game more great.
Thanks
