The focus for singleplayer / coop is a highly replayable and challenging survival horror. Aliens bob and weave when getting shot, making short controlled bursts a necessity, lest you be caught reloading. Ammo conservation is also a necessary skill, as ammo placement is randomized on map loading, as with all other items, including bandage rolls, stim injectors, and audio cassettes (for saving your game). No two playthroughs are the same. But this is more of a training exercise. My real intentions are to make HM into a Left 4 Dead versus styled gamemode, with a squad of 4 Marines attempting to reach and objective, and hordes of disposable aliens trying to stop them. I want to make it class based, with Marines choosing their loadouts at the start of the game, and Aliens having to wait for and score evolution points as the game progresses.
Some gameplay of the first two levels.
