crowbar/rowbar.. does no damage. allows you to move your boat slightly. it is a normal crowbar. should cost around 2000.
prop healer-10000, heals props. .5 or 1 hp per hit
shotgun.. is the normal hl2 shotgun. 22,000 cost. great for close range. bad for far range.
other machine guns.
-ar2 good
-ak47 better
-mp5 amazing
a gravity gun as a weapon. this should cost a lot.
powerups. such as health boost and or speed boost that u have b4 roudn starts.
special props that cost a lot, but have a lot of health.
theses props should float so they cant be used for a tower.
ps. the para gun seems crappy. for cryin out loud the tmp is way better than it ( and it costs like 8 times less)
