Very fun core loop.
Models could use tweaking. The art is very clearly AI generated, but it doesn’t look bad at all. The movement is what looks off. Perhaps instead of forcing the marines to run back and forth, they could be given a sort of teleport effect to traverse? They look really nice, and that running animation just sort of breaks their unmovable stoic look a bit. The enemies attacking the backline was a surprise, but makes for a good change of pace as opposed to the typical “all enemies come from one side” approach that other games like this tend to take. Maybe allowing them to flip direction faced as opposed to their guns rotating 180 degrees could help keep them looking sharper?
Aside from the animations, the weapons could also use some touching up. They just look too similar to really make it appear as though the marine equipped with it is actually playing that role I.E. The Heavy marine equipping the heavy mass gun, it just doesn’t look heavy enough, and as with the grenade launcher and plasma rifle, they just all look like slightly modified versions of the original base rifle. Aside from that I really like the specific classes being built out here, and I’m sure there are tons of directions you wish to take them. That’s exciting.
In the end, you’ve got a nice first build. The foundation is there, and I’m hoping you get to build what you imagine should rest on it.
Best of luck 👍
