Retro Tanks is a 4 player local co-op tank skirmish game with a focus on mining various types of ore to upgrade your tank. With plenty of features such as game customisation, multiple weapons and upgrades, team-play mode, 3 vs 1 mode, single player time-attack mode, post game statistics and ribbon awards/medal system (achievements) which unlocks further game content, tank build-tester and plenty more. There's around 50 levels at present which are played in either campaign mode or free level select. The campaigns are 10 levels long and dedicated to specific set-ups, e.g. team-play campaign for 2 vs 2 games with each level carefully designed to create a tight co-op battle arena.
Design for Campaign 1 Level 2 pulled straight from the level editor (build tool only, won't be in main release). Introduces warp gates and the moderately scarce ore, 'Greenium'. Focus of these early levels is still on getting used to the controls and mining resources rather than all out battles. Additionally, by providing a private reserve of resources (including Blumium & Greenium), it helps avoid having any players fall behind in the early game too much.
