It is an old game that has top down view of combat. You can have a large arsenal of weapons and vehicles to choose from to fight each other. There are many maps to choose from and an active developer community. I recently look it up again because I couldn’t find a similar game on flash based games.
I’ve tried many MMO flash game that involves soldiers fighting on kongregate and other sites. What I find in common is the crazy lag that comes with these games. Multiplayer games are ok, don’t get me wrong, but flash (or even html5) just aren’t ready yet for real time multiplayer games.
The community for infantry is growing, and hopefully I’ll see you guys on there. Screenshots and videos are on the way.
