The game features challenging campaign missions where enemy numbers are superior; additional characters are unlocked but no upgrades are to be found. Skirmishes against relatively poor AI and online asynchronous battles are also available. The gameplay is an almost exact replica of Frozen Synapse: orders are issued to each unit, then five seconds of real time is played out before new orders can be made. Double-clicking adds a waypoint for a unit to follow, which right-clicking access the order menu. Commands include free fire, hold on sight, look, spring, crouch, and wait. The 3-D graphics make it more difficult to spot cover quickly. The only innovative feature is a roster of twelve mercenaries, divided into four weapon classes (shotgun, revolver, grenade, sniper) and each given a different special ability (faster sniper aiming, busting through walls, using flash grenades, et cetera). Still, unit special abilities and a 3-D presentation are not enough to differentiate TASTEE: Lethal Tactics from its obvious inspiration.
