Yeah i have considered all of these things, im am looking into the idea of a landscaped beach, i also have made the wooden ramps, i did that a while ago but forgot to put them in while building the level, but yeah! XD
Also the explosions and constant firing, i have my methods XD ill reveal how i did it later, but ive managed to find a way to make random explosions occur, on the beach, within a certain radius of the player, it adds to the atmosphere and can cause some damage, as for the firing, ill make the enemies shoot continuously from distance, 2 should do as they will only fire upon you, ill only make 3 live allies and several others that are stranded on the beach, but will not move or shoot, just for affect, as well as dead ones, to populate the beach, the enemy gunner should be enough as the explosions will do most of the damage anyway, but its not entirely impossible this mission, but you will end it with severe damage done to you
My only issue really is frame rate, im trying my hardest to keep the poly count down, and with the grid size available on FPSC, its damn near impossible to make an acceptable sized environment
